Nighttime work and traffic detours begin on 2nd and 3rd Streets South next week

2nd & 3rd Streets South

The city of Nampa is adjusting construction activities on the 2nd and 3rd Streets South Roadway Rebuild project to stay on schedule. Beginning Tuesday, May 22, construction crews will remove the top layer of asphalt (called milling) on the south sides of 2nd and 3rd Streets South.

Motorists will drive on the milled surface until the north side of 2nd and 3rd Streets is repaved in late May/early June. Once that occurs the north side will be reopened to traffic and all construction activities will shift to the south side of 2nd and 3rd Streets South.

The roadway will be closed to traffic from 7 p.m. to 7 a.m. and traffic will be detoured around the project area during the milling operations. The decision to begin the milling process now is due to the limited availability of equipment in the Treasure Valley.

For westbound traffic on 2nd Street South (Detour 1 on the below map) traffic will be detoured via 16th Avenue South to 7th Street South to 12th Avenue South (SH-45).

For eastbound traffic on 3rd Street South (Detour 2 on the below map) traffic will be detoured via 12th Avenue South (SH-45) to 7th Street South to 16th Avenue South.

Downtown Map - Detours

The rebuild is needed to improve the severely deteriorated pavement. Sidewalk corners will also be improved to fit Downtown Historic Streetscape Standards and to comply with the Americans with Disabilities Act (ADA). Several underground utilities are also being upgraded.

The $2.8 million project is scheduled to be complete in late August. The contractor is Idaho Materials and Construction of Nampa.

The city will continue to provide updates about the project at If you have questions, please call 208-465-2221 or email
