Spring and summer road work is on its way— but with improvements comes the inevitable—temporary impacts on Ada County roadways. Some $13 million in spending is planned to construct improvements this spring and summer. More than half of the spending will go toward pavement resurfacing projects to extend the life of Ada County roadways, while improvements are planned for five intersections to reduce delays and increase safety.
Two projects are getting underway this week— a new traffic signal at the State Highway 55 and Hill Road intersection in Eagle and resurfacing work on three road sections in Boise.
In addition, ACHD will perform its annual chipseal maintenance starting in July.
State Highway 55 and Hill Road Intersection Signal Project (Eagle)
Early May through late June
Estimated construction cost: $261,000
The project will increase safety with the construction of a traffic signal at the State Highway 55 and Hill Road intersection where stop signs on Hill Road currently control traffic. Right turn lanes will be added to the north, south and east approaches of the intersection and crosswalks will be included in the project, which is being constructed in conjunction with the Idaho Transportation Department (ITD). ITD has jurisdiction over State Highway 55.
Road Resurfacing (Asphalt Overlays)
Early May through fall
Estimated construction cost: $ 4.4 M (locally funded) $3.9 M (federally funded)
Overlay work is planned for 24 road segments throughout the spring, summer and fall months. The maintenance work includes the removal of existing asphalt and the application of new asphalt. Upgrades to pedestrian ramps will also be made to comply with Americans with Disabilities Act (ADA) standards. The overlay process helps to protect the roadway and provides a smoother driving surface. Some overlay work will be done at night to reduce impacts to motorists. Work on the following locations will begin this week or thereafter, while additional locations will follow this summer:
- Orchard Street, Gowen Road to Wright Street – night work (8 p.m.-5 a.m.)
- Five Mile Road, McMillan Road to Treeline Street – day work (8 a.m.- 4 p.m. and 6 p.m.- 10 p.m.)
- Northview Street, Cole Road to Curtis Road – day work (8 a.m.- 4 p.m. and 6 p.m.- 10 p.m.)

Ten Mile Road and Ustick Road Intersection (Meridian)
Mid-May through September
Estimated construction cost: $1.5 M
The project will increase safety and reduce congestion by widening the intersection to include additional through lanes, left and right turn lanes and bike lanes, and installation of a traffic signal. Sidewalk will also be constructed at the intersection. Utility work, including Meridian Public Works sewer and water upgrades will be done in conjunction with the intersection project.
Maple Grove Road and Franklin Road Intersection
Mid-June through late September
Estimated construction cost: $ 1.2 M
Work at the intersection will include the addition of right and left turn lanes on each approach to reduce congestion, a new traffic signal system, and curb, gutter and sidewalk. Structural retaining walls will be constructed on three corners of the intersection to support the slope of the roadways.
Main Street Pavement Rehabilitation Project (Meridian)
Mid-June through late August
Anticipated construction cost: $1 M
The pavement on Main Street between Franklin Road and Cherry Lane is failing and needs to be replaced. The project will remove the existing asphalt and apply a new layer of asphalt. Roadwork is anticipated to occur at night to reduce impacts to motorists. Upgrades to the pedestrian ramps will be done during daytime hours.
State Street, Collister Drive to Veterans Memorial Parkway Pedestrian Improvement Project
End of July through early November
Estimated construction cost: $250,000
The project will increase safety and connectivity for pedestrians by constructing a pedestrian walkway on the north side of State Street between Collister Drive and Veterans Memorial Parkway, where sidewalk does not currently exist.
Additional work planned
Two new traffic signals will be installed to replace four way stops at the Ten Mile and Victory and Locust Grove and Victory intersections, beginning in June. Work is expected to take approximately one month to complete. Both projects will include installing a traffic signal and minor road widening at the intersection.
This summer ACHD crews will resurface 75 miles of roadway during the chipseal maintenance season. Work will begin after the Fourth of July holiday and is expected to wrap up in early September.
