Hallelujah! At long last the City of Portland Bureau of Transportation is using an actual curb to separate bike-only lanes from standard vehicle lanes.

For years PBOT has struggled to figure out how to cheaply and quickly add physical separation. They’ve tried using plastic wands but those rarely last more than a few days before they’re hit and ripped out by people who can’t control their cars. PBOT’s most recent attempt to help separate the bike lane from encroachment by motor vehicle operators came in the form of “rumble bars.” Those failed too.

With budgets not willing to spend money required for raised cycle tracks (like the ones on SW Moody Avenue or NE Cully Blvd), finding a quicker-and-cheaper method is really important. We will not reach our transportation, climate, and planning goals unless we create more physically-separated bikeways. It’s a must.

That’s why are very happy to see that PBOT is testing a new product called “Tuff Curb” to separate a bike lane on SW 13th just before Clay. As we reported when they installed plastic wands there back in January, most of them were ripped out within a week.

Their new installation looks really solid. It’s similar to what Multnomah County installed on the eastbound Hawthorne Bridge viaduct back in 2013.

Based on prices for similar products we found online, this project on 13th and Clay likely cost about $4,000 in materials. Here’s more about Tuff Curb from a product website:

Tuff Curb is a durable, high performance traffic separator curb… Integral coloration makes Tuff Curb highly visible and resistant to UV damage and fading. In addition, enhanced profile dimensional properties and 3M™ reflectors provide maximum visibility and traffic separation both day and night. Tuff Curb’s safety and durability has been tested by Texas Transportation Institute to 2009 MASH standards and is also federally approved.

This is an encouraging sign. Not just because the bikeway at 13th and Clay is now more comfortable to ride in, but because PBOT has taken the time and resources to figure this out once and for all. Using this new plastic curb product shows that Portland is treating bikeways with the level of seriousness they deserve.

If you’ve ridden by it, let us know what you think. It’ll be interesting to see if they use it anywhere else. And if it lasts more than a week.

Stay tuned.

Very nice. It looks like the wands are replaceable, too? (not that a vehicle would *still* manage to hit them or anything…)

Opus the Poet

They shouldn’t be “replaceable” they should be heavy wall steel and set deeply in and filled with concrete. Garaundamntee you that it won’t take more than 2 cars getting the right front corner taken off to get cars to stay the hell out of the bike lane.

I’m sick and tired of “protected” bike lanes that wouldn’t stop or even noticeably slow down a vintage VW Bug (with the original 12 HP engine) driving through the “protection”. Put in the steel bollards at random intervals and locations, and make the plastic wands look exactly like them so the city doesn’t have to spend as much on the steel ones, and eventually the city won’t need more than 2 or 3 steel ones per block, just to remind drivers that bike lanes are not for cars.

This treatment looks very nice. It works well on the Hawthorne viaduct so I see no reason why it can’t work anywhere else. Perhaps PBOT finally has a solution to the Couch curve? I can think of a couple hundred other places to install these around town as well, so here’s hoping the manufacturer offers a bulk discount!

Speaking of the Couch curve, are the developers of Slate reconnecting Couch from the curve to 3rd for cars??? If so, that’s totally NOT cool.

They are building a new street (NE Couch Ct) that will connect the curved section of Couch to NE 3rd. The street will be one way westbound, with a contraflow bike lane eastbound.

I use 3rd for my commute and am definitely not looking forward to the extra traffic. I was hoping it was going to be eastbound only for motorists.

Agreed. That’s a terrible idea. I commute through there daily on my bike too. There’s no way that configuration can be made safe.

Leading bike interval on Couch at MLK will help this by giving riders a head start through the curve before drivers.

I will appreciate having a way to cut over to the bridge westbound from 3rd Ave without having to go all the way around to Davis (and then risking the streetcar tracks on MLK for 1 block).

I dunno, I think it looks like a pretty solid solution for short stretches of road – like the example shown. In a situation like this intersection, I don’t mind being kept 100% in for a span of 10 or 15 yards as I approach the corner. If I don’t want to be in the bike lane at that point, I will have already made up my mind and changed lanes earlier. I wouldn’t be thrilled if it ran the entire length of a a block, however.

And the curb is, in fact, easily mountable by a typical automobile – much the same as most other curbs. That is largely the nature of curbs. This will probably be true of just about anything short of a wall, but at that point we’ve gone from relatively easy, quick and inexpensive to difficult, slow and spendy.

Looks great, seems like an improvement over the other methods. Only thing I would add is little smooth steel ball on the end of each wand so that if a car hits them they would put a reminder dent in the car’s hood, fender or grill to keep the driver from being careless next time,

$4000? I should bid on these projects.

Behold, my solution:

Place one. Then place plastic bollard. Then place one. Then place plastic bollard.

$62 + $50 + $62 + $50 = $224

I’ll do it for $3,500.

Rent on the concrete drill?
Your hourly wage, BOLI, liability insurance?
Bonding?
Self employment taxes (SS/Medicare/Income; state; local)?
work zone traffic control plan and signing/set up and removal?
epoxy for the holes you drilled?
lag bolts for the epoxied holes?

While that’s all true, Jonathan’s $4000 number was for just the materials, too. It is pretty high considering the materials/technology involved, but that’s the nature of a niche product. Hopefully it will grow and scaling/competitors will drive the cost down.

You forgot that all government contract works requires employees be paid prevailing wages.

But here is a brief rundown of some of the tools that would be necessary and their costs (I do stuff like this for living).

1) Truck – variable cost. as much as you’d like to perhaps do this by bicycle the tools are too much even for cargo bicycles, and should something happen and you need to make a quick trip for more epoxy midway through the install you wouldn’t want to waste the time of the likely 4-6 person crew hired (again at prevailing wage).

2) generator – at least $1000 for a reliable one, this doesn’t include the fuel or maintenance costs.

If there is any welding involved in the install you’re looking at around 5k for a decent basic commercial set up, and look at paying at least $100.00 an hour for a prevailing wage welder (including workman’s comp and all that back end payroll stuff). The welding machine I use uses roughly 5 -7 gallons of gas a day when ran for an entire 8-hour shift. And needs to have the oil changed every 100 work hours (or about every two weeks).

3) roto hammer – $300+

4) bits for roto hammer $20+ (I’ve spent as much as $200 for a single bit) each is good for about 100 holes each but that varies too depending on the material being drilled into.

5) extension cords – 100′ of 12 or 14 gauge wires for outdoor use about $50.00 each. Use of smaller sized cords will cause your tools to burn out.

6) epoxy – depending on what is required by the engineer, you’re looking at $30 – $50 a tube not including the gun for the application which runs $100 from Hilti or I think about $25 for Simpson (note these are for the hand operated ones, there are automatic ones too which cost significantly more).

A tube from either manufacturer will fill about 5-20 holes depending on hole size. If there are cracks and their size is significant enough you need to screen the holes which are also brand-specific and cost around $10.00 each and even then they still use much more epoxy than standard holes.

7) Quality air compressor for cleaning out the holes, good ones for commercial work run about $300+ (not including the hoses and attachments), the cheapies will burn out on you very quickly.

8) steel bristled bottle brushes also for cleaning the holes which run $5 -$20.00

9) you’ll also likely need a decent corded impact wrench – $150+, and a full selection of bits and extensions for it another $100.

Let’s not forget that installing epoxy requires full-time independent inspection (add another person whose job is to just watch and assure installation was done properly – at a likely cost of $40-70 an hour I don’t know at what cost inspection companies bill but I do know roughly how much inspectors make).

That doesn’t even get into traffic control which will be at a minimum of 1 flagger (on a one-way street) candle sticks (tall skinny cones) , signage, and temporary barriers and possibly fencing. More than one flagger would also need walkie-talkies.

I should also add parking stops are designed for controlling traffic traveling at full speed. Many of the concrete ones don’t even anchor into the ground and would slide if hit at full speed.

I did a quick search for ‘Bike Lane Sweeper’ and discovered that Portland has (had?) one!

The more separated lanes the more of these that will be needed. One certainly doesn’t cover what we have well, and even unprotected lanes only get swept when they do the roads, which isn’t often enough.

In my area it would be great if it were done after every recycling day. The trail of glass shards is amazing.

tedder
Guest

on the bright side, protected lanes shouldn’t get as much displaced crap from road lanes- gravel and glass, for instance. certainly there will be junk, but not so much derived from the cars.

those little sweeping vehicles are cute.

Steve Scarich

Good point. Over here in Bend, I have noticed that ‘non-standard’ curbing ends up trapping lots of debris. Street sweepers are too big to clean it properly, so we now have several years of crap built up next to them.

I guess ‘If it makes you feel good, it is good ! ‘, is the reaction hoped for here.

This cleverly designed curb material doesn’t make a main lane adjoining bike lane, a protected bike lane. The material may help discourage some inconsiderate people driving, from veering across the bike lane at the last moment, in front of someone biking. Maybe that’s enough to justify the use of this material.

There are people, I expect, that will drive over this type of physical separation, just for sport. Let’s see some video of motor vehicles driving over the material. Watch for the big ‘ka-bump! ‘, with the vehicle possibly lurching wildly, that I expect will happen when a vehicle goes over the material. Will the person operating the vehicle, correct its direction of travel and return to the lane they were in? Or try to fully complete the crossover? On a bike, I think I’d rather not be near a motor vehicle, should a crossover incident like that happen.

most people are less willing to have their car damaged by a wand than they are to stay out of other lanes, I think.

On SW Farmington it is a concrete curb, but it’s also multi-use and not a bike lane only. And it’s only on the south side of the street.

The wands – either:
() make the base attachment a flexible stretch spring that pops the candlestick bollard back in to place
() Or use uniquely identifying STICKY confetti/glitter (like are spread around every time a Taser(tm) is shot with micro printed serial #’s) on each bollard so that damage of public property can be tracked back to a single vehicle. Even if it can’t be tracked back to a person for ticketing the cost of repairs can be tacked on to annual vehicle fees.

() or both.

barbed wire that scrapes the paint might be sufficient.

BZZZT! NO!

Bicycle rider could fall against this at speed definitely injuring and potentially killing them.

Also, scraping and scratching property damage to automobiles is so common no one could ever localize it to any geographic location in particular.

speaking of new, that quote doesn’t seem to have provenance before 1995.

decided to ride through this on the way home… people weren’t driving over it, and they waited for bike traffic before turning…

my worry is that there are a lot of poles obscuring the ability to clearly see bikes in the bike lane…

the worst part was the few blocks leading up to it… several cars blocking the intersections and bike lanes with their incomplete turning movements…

but this change seems like it will work better to keep people out of the bike lane there… and sharp corners like that seem to make drivers think about why it’s such a slow sharp corner…

I appreciate the effort and like the concept, but some things designed to improve bike safety introduce crash hazards that are worse than the crash hazards they reduce.

I believe this particular solution falls into that category.

It works fine on the Hawthorne viaduct. AFAIK, it hasn’t caused any issues there.

Seems like we should have these (or jersey barriers or curbs…anything!) everywhere where there is high speed traffic and no parking on the side – e.g. Greeley between Going and Interstate and going up the hill on Interstate to Kaiser Permanente.

People have been injured and killed on these sections before because there is no separation between 50+ mph traffic and bikers. There is no reason for this.

In a related note – there is still no safe way to directly bike from Swan Island to the Broadway Bridge.

Seems to me that the Tuff Curbs should be painted bright yellow to make it stand out from the road surface, not white. The wands, too. If they’re reflectorized, they should be yellow, too.

And a reminder: there should be a “No Right Turn for Bikes” sign there, since the ramp connects to a freeway (US-26) that is closed to bike traffic. Especially important for out of towners who may not know that!

Yellow is designated for center lines between oncoming traffic, white for fog lines, shoulders and bike lanes.

Glad to see this happening. Unlike Portland, Seattle (where I lived before I moved to Portland) uses barriers like this all over the place, not just to protect bike lanes but to separate opposing lanes and even left turn lanes in places. It’s not like Portland gets more snow than Seattle.

Most of Seattle’s lane separators are concrete (and painted either yellow or white, same as the paint/thermoplastic they replaced), but even back in the 90s I remember them using plastic ones in places. Actually, I think some of the concrete ones have bolt holes, so presumably they could be installed just about as quickly and cheaply as the plastic ones.

Also, after a year-plus in Minneapolis, where we have lots of protected bike lanes where the bollards are *NOT* getting knocked down, I’ve finally realized why: Portland has been putting up bollards to try to keep cars out of the bike lane on curves and turns. Minneapolis only uses them on straight stretches (North Plymouth, W 36th near Uptown, and the East 26th/28th couplet in south-central come immediately to mind). Bollards alone are simply not enough to keep drivers from drifting to the inside of turns/curves, such as 13th or the Lovejoy Ramp.

This looks promising. The far end of this installation is likely to be vulnerable to cars and trucks turning a little too tightly … though I appreciate that they installed it all the way to the crosswalk. I would wager that the last couple of pieces are busted up within a couple of weeks.

How about something more substantial just for the last 6 feet or so? One jersey barrier at the end? Or at least use pieces that are a different color? I wonder if Tuff Curb makes slightly taller versions for end caps and other areas that may need some delineation from the rest of the line.

Generally great idea and will likely be an improvement. We should all keep in mind that they will not stop an encroaching car when something unexpected happens.

From a driver’s perspective, I thought they were more imposing than traditional wands or raised tracks like on Cully, both of which have historically been driven over. So I think from a psychological standpoint, this driver does not want to get close to them. Additionally, I did not have any difficulty performing my normal check the bike lane measures.
