BELLEVUE – Traffic is flowing again across Lake Washington on State Route 520 following a weekend-long closure for construction. The highway reopened to westbound traffic at 3:30 a.m. today, Feb. 10, and to eastbound traffic at 5 a.m.
During the closure, crews working for the Washington State Department of Transportation performed a variety of time-sensitive upgrades within SR 520’s Eastside corridor. One job was the realignment of highway lanes in both directions between 92nd Avenue Northeast and I-405 – a shift to accommodate other needed construction work in coming months. Workers also installed new electronic signage over the highway, noise walls, utility lines, and storm water pipes.
In addition, other crews poured concrete for support columns of a new West Connection Bridge. This structure will join the highway’s existing lanes in Seattle with the west end of the new SR 520 floating bridge now under construction.
The Eastside Transit and HOV Project is part of WSDOT’s larger SR 520 Bridge Replacement and HOV Program. Between Medina and I-405, crews are widening SR 520 to six lanes, rebuilding interchanges, constructing neighborhood-friendly highway lids, building in-median transit stops for the corridor’s new transit/HOV lanes, and installing fish-friendly culverts beneath the highway.
The reconstructed Eastside corridor is expected to open to traffic in late summer. The new floating bridge is planned to open in early 2016.
