Drivers advised to prepare for delays on Highway 99 for pavement preservation project

Intermittent delays between Northeast 78th Street and Northeast 134th Street scheduled to begin Mon., Aug. 19

VANCOUVER — Frequent travelers of Highway 99 should prepare for intermittent delays between Northeast 78th Street and Northeast 134th Street beginning Mon., Aug. 19.

Drivers can expect intermittent, single-lane closures throughout the project area while crews with Clark and Sons Excavating perform pavement repair and crack-sealing work throughout the corridor. Work will be done between the hours of 8 a.m. and 8 p.m., Monday through Friday.

This work is fast-paced and mobile, so travelers can expect the delays to occur briefly at many different locations within project limits. Crews expect to start at Northeast 78th Street and move northbound until work is complete later this fall.

These improvements are the first phase of a $4.3 million project aimed at improving accessibility and mobility along the heavily-traveled corridor. Later this year, contractor crews will complete ramp construction to bring sidewalk ramps up to current Americans with Disabilities Act (ADA) standards. ADA compliance work will require some nighttime closures of intersections throughout the project area. Next spring, crews will come back to the same corridor to complete paving operations.
