More details on Morrison Bridge bike improvements: Construction starts next week

The (very) long-awaited bike and pedestrian improvements to the Morrison Bridge will begin construction next week.

In the plans are a 15-foot wide shared path that will be added (only) to the south side of the bridge (it will be a two-way facility), from SW Alder Street to SW Naito Parkway on west side and SE Water Ave. on the east side. This $1.9 million project will vastly improve biking conditions on this bridge. Currently, the Morrison has only five-foot sidewalks (even narrower at pinch points) on each side.

According to Multnomah County, the Morrison Bridge has the lowest rates of bike use of the five downtown bridges. For comparison, the most popular bike bridge, the Hawthorne, has a 10-11 foot wide bike/ped path in each direction.

If you ride on the Morrison, note that Multnomah County plans to close the south sidewalk during the project but the north sidewalk will remain open.

In addition to the new bike/ped facility, planners say this project will improve safety with the construction of a new intersection. The current bridge off-ramp on the eastside merges with an I-5 off-ramp at SE Water Ave. The new intersection will be about 70-feet north of the freeway off-ramp.

Also improving safety will be a two-foot tall concrete wall with a one-foot metal “pedestrian rail” on top of if. The “crash-worthy” barrier will run from the top of the ramp at SW Naito all the way to the top of the SE Water off-ramp.

Other new features in store with this project include (for reference, here’s a link to a Google Map of the bridge):

The project is scheduled for completion by the end of this year.
