Motorists should expect brief delays this week as Richland's contractor resumes work on the Keene Road project after a winter hiatus.
Crews from Apollo Inc. will finalize roadway grading before placing the roadway's base rock.
Later in the week, crews will finish the last underground work, including a storm line crossing of Keene near Lethbridge Avenue that will close one lane.
Drivers should plan for five- to 15-minute delays and periodic closures of Jericho Road.
Never miss a local story.
Keene Road carries 12,000 to 13,000 cars a day, so city officials recommend motorists allow additional time to reach their destinations.
Richland began the yearlong project in September to widen Keene Road from two to five lanes between Queensgate Drive and Tomich Avenue.
As part of the $3.1 million project, crews also will lay fresh asphalt on Queensgate Drive between Keene and Interstate 182 and add a traffic signal at Keene and Kennedy Road.
Benton County helped fund the Queensgate Drive repaving and West Richland contributed to the new traffic signal.
The project also includes bicycle lanes, a south-side sidewalk, a multiuse pathway on the north side, landscaping and street lighting.
Crews also are replacing a water main from Country Ridge to Tomich and installing a sewer main from Lethbridge Avenue to Tomich.
Information on this and other Richland projects that affect traffic is available on the city's website at ci.richland.wa.us and on a recorded phone line at 942-7738.
