The speed limit on Barbur Boulevard will be reduced to 35 m.p.h.
in the construction zone, 24 hours a day.
During construction this spring and summer, motorists and bicyclists can expect the following impacts. This construction schedule may be modifed. More specific information on closures and detours will be available at the open house. Check back here later March for more details. All closures will be publicized in advance.
· There will be daytime and nighttime single lane closures on both bridges, in both directions.
· Vermont Street bridge: All southbound lanes may be closed for approximately four weekends – motorists will be detoured to Capitol Highway (OR 10) and Bertha Boulevard. Northbound traffic will be reduced to one lane.
· The intersection of Barbur Boulevard and Parkhill Drive will be closed periodically; a signed detour using Terwilliger Boulevard will be available for residents.
· Bicycles will not be required to detour off Barbur Boulevard at any point during construction.
· The walkways across the bridges will be closed to bicyclists and pedestrians periodically.
· The TriMet bus stops near the bridges will be closed during construction.
Newbury and Vermont Street Bridge Deck Repairs
Construction Issues and Solutions
Problem: The concrete pavement next to the bridge deck joints across both bridges has deteriorated. This has allowed water to get inside the joints, rusting the steel rebar inside the bridge deck and causing other damage.
Solution: Repair the concrete deck at the bridge joints. ODOT will improve drainage and improve the ramps leading to the existing walkways.
Problem: The drains on the bridge decks regularly get clogged with dirt and debris, causing water to run across the bridges resulting in standing water.
Solution: Improve the drainage system on the bridges.
Impacts: The highway will be reduced to one lane in each direction during the day and will reopen fully to traffic at night. Lane closures will occur during the day. Bicycles will ride with traffic in shared lanes during lane closures.
Construction Duration: All of the above work will take approximately 18 months. This may be shortened. More information will be availabe in late March.
Vermont Street Bridge Cap Replacement
Problem: The Vermont Bridge has wooden caps at both ends of the bridge, which are rotting and cracking due to water seeping in over the last 78 years. If these caps are not replaced, the bridge will be weight restricted – preventing heavy vehicles, like trucks and Tri-Met buses, from using this part of Barbur Boulevard.
Solution: Remove the old wooden caps from both ends of the bridge and replace them with steel caps.
Impacts: This work will require closure of half the bridge for up to four weekends to complete. Northbound bikes will ride with traffic in a shared lane. Southbound (uphill) bikes will have a separated bike lane.
Construction Duration: The cap replacement work is expected to occur on up to four weekends from 9 p.m. on Friday to 5 a.m. Monday.
