A construction project to modify the I-5 southbound on-ramp at Wilsonville Road is now underway.
This agreement with the Oregon Department of Transportation (ODOT), approved by City Council at the Oct. 16, 2017, meeting, adds a third stacking lane to the metered on-ramp to increase vehicle capacity. The additional lane for the on-ramp is designed to accommodate more vehicles that seek to merge onto I-5 while decreasing traffic congestion at the I-5/Wilsonville Road interchange area.
“When completed, the on-ramp will accommodate about 25 additional vehicles during the evening rush hour,” said Mike Ward, civil engineer. “Provided the project stays on schedule, construction should be substantially complete by the end of May.”
Construction of the third stacking lane is to be completed during off-peak hours in order to minimize the inconvenience to motorists in and around the Wilsonville Road/exit 283 interchange.
At 7 p.m. each night, one lane of the current two-lane Wilsonville Road southbound on-ramp is closed; traffic enters the on-ramp in a single lane overnight until 6 a.m. on weekdays, 8 a.m. on Saturday or 9 a.m. on Sunday. The shoulder is closed for the duration of the project.
The project, estimated to cost approximately $700,000, is one of three congestion improvements designed to improve traffic flow and reduce congestion on Wilsonville Road between Boones Ferry Road and the I-5 interchange. The other two projects include lengthening the southbound Boones Ferry Road double left-turn lanes onto eastbound Wilsonville Road, which is complete; and reconstructing the southern, signalized entrance/exit to Old Town Square/Fred Meyer shopping center to include a second travel lane on northbound Boones Ferry Road between the exit/entrance and Wilsonville Road.
