The Oregon Department of Transportation brushed aside proposals to allow safe bike travel on Southwest Barbur Boulevard, raising the possibility of “unacceptable impacts” that might result from replacing a northbound travel lane with dedicated bike lanes.
“While some have framed the removal of a motor vehicle lane on the bridges as a quick and easy, ‘noimpact’ solution, there are impacts that need to be considered,” the agency wrote in a memo distributed Thursday evening.
The memo cited estimates that removing one of Barbur’s four travel lanes would increase northbound auto travel times between 5 and 15 percent today, and somewhere between 10 and 65 percent by 2035.
During the busiest few minutes of the morning on the 4.9 mile corridor in question, it comes out to an additional delay of somewhere between 84 seconds and 9 minutes over the course of the next 22 years.
Update 8:03 pm: I’ve changed these figures (previously 1.8 miles and 36 seconds to 4 minutes) to include the full stretch of road studied and to allow an apples-to-apples comparison of travel times in 2035. -MA
“The actual amount of delay would likely fall somewhere in between these two predictions on ‘typical’ travel days,” the memo from ODOT’s Jessica Horning explained.
Barbur currently forces cars and bikes to merge into the same lane as they cross two narrow bridges on Barbur. The speed limit on the bridges is 45 mph.
