Preventive maintenance continues to play a key role in preserving highway infrastructure and extending pavement life. The Idaho Transportation Department (ITD) is beginning a pavement preservation project along Interstate 84 that will improve roadway durability while minimizing the need for more extensive rehabilitation in the future.
Construction will begin July 13 along I-84 between the Idaho-Oregon state line and the Black Canyon Interchange at Exit 13.
The project includes applying a hot chip seal to the interstate and chip sealing interchange ramps throughout the corridor. Construction will occur overnight, with crews completing westbound lanes before shifting operations to the eastbound roadway.
Work hours are scheduled from 8 p.m. to 7 a.m. on westbound I-84 and from 8 p.m. to 9 a.m. on eastbound lanes.
Motorists should expect single-lane closures in one direction at a time throughout construction.
Ramp closures will occur for three consecutive nights at each interchange as preservation work progresses. Temporary detours will direct traffic through U.S. Highway 95 and U.S. Highway 30 where necessary. The Snake River View Welcome Center will also close overnight for three consecutive nights while nearby work is completed.
A temporary 60 mph speed limit will remain in place during construction to improve safety and reduce the risk of vehicle damage.
The project is expected to conclude by the end of August.
Pavement preservation programs help transportation agencies maximize the service life of existing highway assets while reducing long-term rehabilitation costs. For contractors and infrastructure owners, preventive maintenance projects such as chip sealing remain an important component of asset management strategies that improve roadway performance and defer more costly reconstruction.
