The Oregon Department of Transportation (ODOT) will be rehabilitating two bridges on SW Barbur Boulevard (OR 99W), just south of Capitol Highway. Construction is scheduled to start in early 2014.
The Newbury Street and Vermont Street bridges were built in 1934 to cross two ravines. Both are in need of repair due to water seeping inside the joints which causes the steel rebar inside the bridge deck to rust as well as other damage.
ODOT will repair the concrete deck of both bridges at the bridge joints. In addition, ODOT will improve drainage, improve the ramps leading to the existing walkways, install a taller safety railing, and replace signs on both bridges.
In addition, the Vermont Street Bridge is one of only a few bridges in Portland that still has wooden caps, which bear the weight of the bridge at both ends. The caps are rotting and cracking due to water seeping in and around them over the years. If these wooden caps are not replaced soon, the Vermont Street Bridge will be weight restricted, which would prevent heavy vehicles, like trucks and TriMet buses, from using this section of SW Barbur Boulevard. This project will replace the wooden caps with steel caps.
Construction Impacts: There will be up to 30 nights of construction work during the project, in addition to daytime work. The entire project is expected to be complete in 18 months.
Building this project will be very challenging, due to the narrowness of the bridges and the high traffic volumes on Barbur Boulevard.
Overall, this project will:
• Grind and repave the decks of both bridges
• Replace the wooden caps on the Vermont Street bridge with steel caps
• Remove and replace the concrete next to the 29 joints that cross the decks of both bridges
• Install taller pedestrian/bicycle safety railing on both bridges
• Add “Bikes on Bridge” flashing warning signs to increase safety
• Improve the ramps leading to the walkways and curbs on both bridges
• Improve the drainage systems on both bridges

Traffic Impacts from Construction
ODOT will provide plenty of advance notice prior to any traffic restrictions.
During construction, motorists and bicyclists can expect the following impacts:
• Half of each bridge will be closed for construction and southbound traffic will be detoured for up to four weekends.
• Motorists heading southbound, only, will be detoured to Capitol Highway (OR 10) and Bertha Boulevard for four weekends.
• Northbound traffic will be restricted to one lane for up to four weekends.
• Daytime and nighttime single lane closures will occur on both bridges, in both directions throughout construction.
• Bicycle access across the bridges will be open throughout construction.
• The walkways will be closed to pedestrians, periodically.
• The intersection of Barbur Boulevard and Parkhill Drive will be closed periodically.
• Temporary closures of the TriMet bus stops between the two bridges will occur during construction.
There will be up to 30 nights of construction work during the project, in addition to daytime work. The entire project is expected to be complete in 18 months.
ODOT received a Noise Variance from the City of Portland for night work on this project.
Work that occurs at night will include:
• Replacement of timber caps on Vermont Street Bridge --up to 16 nights of work
• Grinding and Paving of the bridge deck--up to 14 nights
To minimize the impact of nighttime noise ODOT is required to do the following:
• No back-up alarms on construction vehicles and equipment after a certain time at night
• Regular testing of noise levels from several different receptor locations during construction
• Advance notice of nighttime work provided to nearby residences and businesses
• A 24/7 hotline phone number is available for people to call to report urgent noise concerns or complaints.
Budget and funding
This construction project will cost just over $3.2 million to complete. Funding is coming from a federal grant and matching state gas tax funds.
