SR 285 - Mission St and N Wenatchee Ave - Paving and ADA Compliance - Complete October 2018

Project news

The project started Sunday, June 24 at 8 p.m. and was complete the last week in October.  Central Washington Asphalt crew's regular work schedule ran Sunday through Thursday nights including lane and intersection closures. The work began with the ADA compliance work. Crews started from the south near Benton Street; working north.   


This project paved and updated sidewalks and intersections to current Americans with Disabilities Act (ADA) standards from the Senator George Sellar Bridge in South Wenatchee through the Wenatchee River Bridges to Olds Station in North Wenatchee.  It also upgraded traffic signals at six intersections on Mission St. and installed fiber optic cable conduit on North Wenatchee Avenue.

The majority of the construction was done Sunday through Thursday nights using only single lane closures from 8 p.m. to 6 a.m. (No full closures).  Daytime work included five weekend closures of side street intersections to reconstruct traffic signals and for concrete work at Kittitas, Yakima, First, Palouse, Fifth, and Ninth Streets.  Bridge deck repair work on the southbound Wenatchee River bridge also required daytime lane shifts Aug. 10-13. Before this project began, to allow for reconstruction of ADA (Americans with Disabilities) ramps, four ramps had to be removed and temporarily filled with asphalt patches so the city could relocate fire hydrants.

The project limits extended from MP 0.79 (between Ferry and Bridge Streets) to MP 5.04 (US 2 overcrossing on SR 285 at Olds Station), skipping the intersection of Miller to Wenatchee Ave. which was rebuilt last summer.

Needs & benefits

  • Mission Street and North Wenatchee Avenue are the highest traffic volume route in the city and deteriorated pavement needed to be rehabilitated and preserved before the roadway itself is damaged. 
  • Traffic signal control needed to be upgraded to replace aging wires and bring pedestrian push buttons up to current American’s with Disabilities Act standards. 
  • Pedestrian sidewalk ramps needed to be brought up to current American’s with Disabilities Act standards.


  • The project was advertised for private contractor bids on April 2, 2018.
  • Contract #9260 was awarded to Central Washington Asphalt, Inc. of Moses Lake on May 14 for $6,069,307.35.
