West Connection Bridge construction continues; grinding work coming up near Madison Park
After nearly one year of construction, the West Connection Bridge is almost complete. Crews expect to finish this interim bridge structure near Madison Park early this fall. Several work activities remain, including grinding the surface of the new bridge deck.
Beginning as early as Monday, July 28, WSDOT and its contractor, Mowat-American Joint Venture, will begin pavement-grinding work on the West Connection Bridge. Grinding will help reduce irregularities in the concrete, improve traction for drivers, and help reduce tire noise once the bridge is open to traffic.
A large grinding machine and hand grinders will be used to accomplish the grinding work. Nearby residents may hear loud, consistent noise similar to an industrial fan. Once crews begin the grinding work, it will take one to two weeks to complete. The work will be performed using construction best practices to minimize noise impacts as much as possible.
Westbound overnight closure scheduled for next week
Crews are continuing planned overnight closures of westbound SR 520 as part of the West Connection Bridge project.
Westbound SR 520 is scheduled to be closed overnight from 92nd Avenue Northeast to Montlake Boulevard in Seattle on the following dates:
• 11 p.m. Monday, July 28 to 5 a.m. Tuesday, July 29
• 11 p.m. Tuesday, July 29 to 5 a.m. Wednesday, July 30
• 11 p.m. Wednesday, July 30 to 5 a.m. Thursday, July 31
Closing both westbound lanes of SR 520 gives crews access to complete the last remaining work activities for the new West Connection Bridge, under construction just north of the existing SR 520 bridge.
Intermittent, overnight, single-lane highway closures are planned in both directions in the coming weeks. For the latest information, visit the SR 520 Orange Page.
Don’t forget the jets: Blue Angels practice and shows mean brief closures of the I-90 floating bridge next week
The annual Seafair festival began when the pirates landed the first week of July, and ends with the Blue Angels flying over Lake Washington in a spectacular display of aeronautics. For the safety of drivers and pilots alike, the Federal Aviation Administration requires WSDOT to close I-90 while the Blue Angels perform.
Which roads will be closed?
Interstate 90 will be closed to all vehicles, pedestrians and cyclists, eastbound and westbound, mainline and express lanes, between I-5 in Seattle and Island Crest Way on Mercer Island:
• Thursday, July 31: 9:45 a.m. - noon; 1:15 - 2:40 p.m. (practice)
• Friday, Aug. 1: 12:15 - 2:40 p.m. (practice)
• Saturday, Aug. 2: 12:15 - 2:40 p.m. (full show)
• Sunday, Aug. 3: 12:15 - 2:40 p.m. (full show)
Note: The bridge highrises will still be accessible to pedestrians and cyclists. However, no one on foot or bike can travel beyond the highrises up to 30 minutes prior to posted closure times.
Note: I-90 east of Mercer Island will NOT be closed during the performance, although drivers should note that heavy congestion during these closures often restricts access to the exits.
The SR 520 bridge will remain open to vehicle traffic and tolls will be collected according to the rate schedule. Drivers crossing SR 520 should expect heavy traffic, significant delays and plan for additional time to cross the lake.
West Approach Bridge North project contract awarded, construction coming next
The new West Approach Bridge North (WABN) project is the next phase of funded SR 520 construction, which is set to begin this fall. As you may know, the current west approach bridge is supported by shallow, hollow columns that could fail in a severe earthquake. The new west approach bridge will have solid columns and be built to modern seismic standards. The 1.2-mile-long structure will connect the new floating bridge’s three westbound lanes, including a dedicated transit/HOV lane and shoulders, to the Montlake interchange in Seattle. The new west approach bridge also will extend a new 14-foot-wide regional bicycle/pedestrian path from the Eastside and floating bridge to Montlake and the University of Washington.
To learn more about WABN, you can watch our new video which highlights some of the construction activities that will take place and the benefits of the completed project to the SR 520 corridor and the entire region.
Out of the five contractor proposals that were received at the end of an 11-week bid period, Flatiron West, Inc. submitted the apparent low bid at $199,537,370, which was below the engineer’s estimate for the project. After close evaluation, WSDOT confirmed that the proposal meets all contract requirements and awarded the contract to Flatiron West, Inc. The contract is expected to be executed in the next 20 days. To learn more, read our news release about the contract award.
After the WABN contract is executed, we expect the contractor to begin construction this fall and open the new west approach bridge to traffic in summer 2017.
