Ada County Highway District construction activity will increase next week on the project to widen Meridian Road to five lanes and shift through-city traffic from Main Street.
The Meridian and Pine Avenue intersection will close 7 p.m. Friday, Feb. 22, and remain closed through early Monday, Feb. 25.
During the weekend closure, vehicles traveling east or west may take Franklin Road or Cherry Lane/Fairview Avenue as alternate routes.
On Tuesday, Feb. 26, work to reconstruct the Meridian/Cherry and Main/Fairview intersections will get underway and will continue through September.
While intersection work is under way, crews will also begin to construct Meridian between Cherry and Pine to its new configuration.
Motorists should expect major delays due to lane closures and a signal timing plan that will allow for left turns to remain during construction, but will significantly reduce the number of vehicles that can pass through the intersection at once.
Crews will put the traffic changes in place overnight on Monday shifting traffic lanes to the south side of the road. Lane closures and the adjusted traffic signal timing will be in place for the Tuesday morning commute.
The $8 million project scheduled for completion in October includes:
• Construction of a crossover roadway, connecting Main to Meridian, north of Franklin and south of the railroad crossing.
• Widening Meridian to five lanes from the crossover roadway north to the Meridian/Cherry intersection.
• Rebuilding the Main/Fairview and Meridian/Cherry intersections.
• Installing new water and sewer lines.
Detour options during the seven-month-long intersection work include Pine, Franklin and Ustick Road.
Businesses closest to the north and south ends of the project may still be accessed from Franklin or Cherry; those within the closure can be reached by alternate accesses established for the project.
A map of business construction accesses and additional information on the road, sewer and water projects is available at www.meridiansplitcorridor.org.
