As part of the south-end Alaskan Way Viaduct Replacement Project – the major work that’s under way now and is proceeding regardless of whatever happens to the Central Waterfront section – weekend closures and longterm lane reductions are coming up starting in less than two weeks. They’ve long been part of the plan, but with two weeks to go, the alarm was sounded this morning by the state Department of Transportation, which is summoning media to a briefing in a few hours.
The closures will happen during the weekend of May 14-15. Longterm lane reductions kick in right after that. WSDOT announcement highlights ahead:
During the closure, crews will set up the new lane configuration and test the new automated viaduct closure system. …
· Friday, May 13 through Saturday, May 14
All lanes of SR 99 between the West Seattle Bridge and the Battery Street Tunnel will close from 11 p.m., Friday to at least noon Saturday.· Northbound SR 99 will reopen between S. Royal Brougham Way and the Battery Street Tunnel at noon Saturday, May 14
The remaining sections of SR 99 between the West Seattle Bridge and the Battery Street Tunnel will reopen by 5 a.m. Monday.
Then:
In two weeks, the State Route 99 Alaskan Way Viaduct corridor will be reduced from three to two lanes both directions between the West Seattle Bridge and Seattle’s sports stadiums.
This work is a critical step toward taking down the seismically vulnerable southern mile of the viaduct within the next year. The Washington State Department of Transportation (WSDOT) has invested $125 million in alternative routes, transit service and traveler information to prepare for this work.
The southern mile of the viaduct corridor will remain two lanes in each direction through 2013 and possibly longer, until the central waterfront portion of the viaduct is replaced. WSDOT is delivering its commitment to keep SR 99 open during construction; however, lane closures have always been a key part of the plan. The lane reduction provides crews working for WSDOT with the space they need to continue construction of the new southbound lanes.
“These long-term lane closures will enable us to take down the seismically vulnerable southern half of the viaduct within the next year,” said Ron Paananen, WSDOT Administrator for the Alaskan Way Viaduct and Seawall Replacement Program. “We ask drivers to plan ahead and make use of the investments we’ve made in transit, alternative routes, and traveler information to prepare for this construction.”
Approximately 87,000 vehicles use this stretch of SR 99 each day, with the heaviest volumes during the morning and afternoon commutes. If traffic volumes in the SODO area remain at current levels, drivers can expect increased congestion and delays on SR 99 during the morning and afternoon commutes. Spillover traffic could also affect alternate routes, including I-5, the West Seattle Bridge and city streets.
WSDOT adds, “Northbound SR 99 will have a dedicated transit-only lane between Spokane Street and S. Lander Street.”
We’ll be at the 11 am briefing for more details on exactly how this will affect commuters and what authorities advise as alternatives.
