Project Description

Project will widen WVH to the east to construct the 3rd NB thru lane & install a 15' wide pedestrian zone where feasible. Lane offsets will be corrected as the NB curb line is brought to a consistent location. Bridging the SPU 60' watermain will be done to traffic load bearing standards to accommodate the widened roadway & the pedestrian zone. The existing NB RT lane that drops at Longacres will be carried through to S 156th St. The inside NB lane north at Longacres will feed directly into the dual NBLT lanes to I-405, alleviating the existing congestion point as the inside lane becomes blocked by heavy turn volumes, making an effective single NB lane. Where appropriate, existing broken s/w panels will be replaced. Pedestrian signalized crossing types will be studied to bring users of the new Ped/Bike Bridge over the Green River (located at 16113 WVH) safely across WVH, including a landscaped median/pedestrian refuge midway between Strander & Longacres. The new bridge (open late 2017) connects the Green River Trail & Southcenter on the west to the hotels & Sounder Station on the east. Driveways will be reconstructed to meet current ADA guidelines. The project will construct wide sidewalks & a buffer zone along the property frontage including the joint King County/Tukwila project to construct widened sidewalks from the Ped Bridge point north to Longacres Way (CMAQ funded). Any new illumination will use LED lamps. Fixed objects will be moved outside the 15' clear zone where possible. Possible access mgmt by changing the TWLTL into a median with u-turns at intersections will be studied.

Project Delay
01/31/2020 The city was unable to reach agreement with the consultant on scope and fee. They re advertised for consultant services and conducted interviews on 4/12/2019, the hope to give the consultant notice to proceed in June 2019. City hopes to advertise Spring 2020 but the project funding package includes federal funds, requires WSDOT approval, a corps permit is requires, and the project crosses 60-inch water main owned by Seattle Public Utilities. Because of these constraints I think it is unlikely that the project will Fall 2020.
