  Construction and Traffic Impacts

See construction phase diagrams below. Construction started on June 10, with full lane closures.  Traffic will be restricted to one lane in each direction 24 hours a day, 7 days a week and continue until the project is complete in the fall.  The closures will be on Barbur Boulevard between the Capitol Highway exit on the north end and Brier Place on the south end.  The result will be more daytime congestion on Barbur Boulevard in this area. 
 
The project website www.barburbridges.org will be updated regularly with the latest information. 
Lower Speed Limit During Construction
 
The speed limit in the work zone will be reduced to 35 miles per hour, 24 hours a day, 7 days a week.  The current speed limit is 45 miles per hour. There will also be increased speed enforcement during the project on Barbur Boulevard.
 
The project website will be updated regularly with the latest information.  The new shorter web address is www.barburbridges.org
 
Bicyclists To Share Wider Travel Lane with Motorists
 
During the daytime construction on each bridge, bicyclists will share a wider travel lane (14 feet versus the current 12-foot lane) with motor vehicles.
 
When feasible, the contractor will open a protected lane for cyclists through the work zone, in the evening and on weekends.  Cyclists may travel this lane on weekday evenings from 4:30 p.m. to 6 a.m. and throughout the weekend, when available.  Signs will direct cyclists when the lane is open. 
 
If the lane is not open, cyclists will continue to share the travel lane with motorists.  Lighting is provided to illuminate the work zone. 
 
Work Affects Pedestrians
The bridge walkways will be closed in one direction during construction on each bridge.  No accommodations will be made for pedestrians in the construction zone.
 
TriMet Bus Stop Closed
The TriMet bus stops near the two bridges will be closed during the project.  The closest stops will be at the Rasmussen Village Apartments at the north end of the project and Southwest 2nd Avenue at the south end of the project.

Construction Issues
 
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.   
 
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.
