Eastbound Interstate 8 Pine Valley Pavement Project

Work on Highway 8 from Viejas Creek to the Pine Valley Creek Bridge began in late July and is expected to go through early 2024.  You can expect nighttime lane closures as well as ramp closures.  The following details will help you navigate the road work.

Nighttime lane closures on eastbound I-8 main lanes continue the week of August 29. Eastbound  I-8 will be reduced to one lane in the work areas as follows:

·       Tuesday, Aug. 30, 9 a.m. to 12:01 a.m.:

o   From West Willows Road to Viejas Creek Bridge

o   From Vista Point to SR-79/Japatul Valley Road

·       Wednesday, Aug. 31, 12:01 a.m. to 5 a.m.: From Horsethief Creek Bridge Undercrossing to Pine Valley Road Undercrossing


The Vsta Point located on eastbound I-8 east of East Willows Road near Alpine is serving as a construction staging area and will remain closed for the duration of the project.

The eastbound I-8 bicycle lane will also be closed during the project for the safety of bicyclists, drivers, and highway workers. Shuttle transportation will be provided for bicyclists from East Willows Road to the State Route 79 (SR-79)/Japatul Valley Road Park and Ride.

The construction schedule is subject to change due to weather conditions, traffic incidents or other construction related reasons. Motorists are reminded to Be Work Zone Alert and watch for highway workers and moving equipment.


The Eastbound I-8 Pine Valley Pavement Project spans a 10-mile section of eastbound I-8 from Viejas Creek to just west of Pine Valley Creek Bridge. The project will replace the right lane and outside shoulder with Continuously Reinforced Concrete Pavement (CRCP), the left shoulder with hot mixed Asphalt, and install drainage improvements.

 CRCP is a process of placing steel reinforcing bars within the concrete along the entire length of the lanes. CRCP naturally forms tight transverse cracks to evenly transfer loads. The result is a continual, smooth-riding surface capable of withstanding the heaviest loads and the most adverse environmental conditions. The life span of CRCP pavement may be up to 70 years, far exceeding current road surfaces. This means a better driver experience with less cost and maintenance time for highway workers exposed to live traffic.

The portion of the project from SR-79 to just west of Pine Valley Creek Bridge will replace the right two lanes and right shoulder with CRCP. The work includes replacing/upgrading guard rails and repairing bridge rails on five bridges. The estimated total project cost is $46.8 million funded by state and federal sources.
