1703 – WSDOT 2018 Mission Paver and ADA Improvements


This section of roadway is due for resurfacing according to the Washington State Pavement Management System (WSPMS). An HMA Mill and Fill of this section of roadway will prevent further deterioration and allow it to be maintained at the least possible life cycle cost. Work will include a mill and fill of the driving lanes, pavement repair, crack sealing, fog sealing parking lanes/shoulders, induction loops, plastic pavement markings, ITS conduit trench, lowering/adjustment of utilities, and other work.

The project starts Sunday June 24 at 8 p.m. Central Washington Asphalt crews regular work schedule will be Sunday through Thursday nights. The work begins on the ADA ramps requiring pedestrian detours while the ramps are torn out and rebuilt. Crews will start from the south near Benton Street and work north. There will be night time lane closures as well so the numerous utility providers can mark their pipe/conduit locations before paving begins.
The following week crews will only work Sunday and Monday nights (July 1-2), then will shut down for the 4th of July holiday until Sunday night July 8 when they will start fiber optic conduit installation in the northbound lanes of N. Wenatchee Ave.

Overview


This project paves and updates 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 in North Wenatchee. It also upgrades traffic signals at six intersections on Mission St. and installs fiber optic cable conduit on North Wenatchee Avenue.

The majority of the construction will be done Sunday through Thursday nights using only single lane closures from 8 p.m. to 6 a.m. (No full closures). Daytime work will include as many as 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 work on the southbound Wenatchee River bridge will also require daytime lane shifts over a single weekend (again, No full closure). 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 outside pedestrian routes.
The project limits extend 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 needs to be rehabilitated and preserved before the roadway itself is damaged.
• Traffic signal control need to be upgraded/coordinated/extended to better manage traffic flow.
• Pedestrian sidewalk ramps need to be brought up to current American’s with Disabilities Act standards.

Timeline


• 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.
• Construction begins June 24 and should be complete in October.

Funding


This (P-1 & I-2) Highway Capital Roadway Preservation and Risk Prevention Safety Improvement project's total funding is $6,807,312.35 of local, state and federal dollars.
