Project Evaluation: US 12, SR 124 to McNary Pool - Add Lanes
Walla Walla County
This project improved US 12 for approximately four miles near the City of Pasco, in Walla Walla County, from just east of the Snake River to just west of Casey Pond.
Two new lanes were added on US 12 to provide a four-lane divided highway. In addition, a two-mile long frontage road was built, a traffic signal system was replaced at the Humorist Road intersection , and a new traffic signal system installed at SR 124 intersection.
The new lanes will reduce congestion, and safety is improved separating opposing traffic by a median or by concrete barrier. Channelization and traffic signals at the Humorist Road and SR 124 intersections with US 12 provide safer conditions for crossing the highway.
Construction Summary
Work began on January 3, 2005. The contractor and WSDOT worked on the project, building approximately 10 lane-miles of new roadway (eight lane-miles on US 12, and two lane-miles of frontage road). On May 31, the two new US 12 eastbound lanes were opened to traffic. In June the contractor constructed intersection channelization and resurfaced the existing pavement on the (now) westbound US 12 lanes.
Progress slowed through the months of July and August due to the contractor's busy schedule, and the contract requirements that seeding operations not be done until October. Work resumed, in earnest, around the end of August. The new signals were in place and functioning by September 14, 2005.
It is anticipated that "Physical Completion" will be attained by mid-November 2005, which is right on the original schedule.
