This project is substantially complete.
Beginning as early as May*, crews will be working overnight to apply a microseal overlay on various streets in Downtown Meridian and Boise. The microseal process involves cleaning the existing asphalt and then applying a fast-drying asphalt-based sealant. Roadways are microsealed to protect them from water and weather damage, so they stay in good condition.
This project also includes installing a two-stage rectangular rapid flashing beacon (RRFB) across Meridian Road and Main Street at Bower Street.
What to Expect During Microseal:
- All microseal work will occur at night (8 p.m. to 5 a.m.)
- Through traffic and on-street parking will be restricted at night while crews are microsealing each road
- Access will be maintained for businesses, hotels, and residents
- Flaggers and signage will direct traffic in the areas where crews are applying the microseal and at adjacent intersections
- Temporary closures
*Due to contractor staffing issues and supply chain shortages, construction schedules could change.
