State Route 4 Pavement Anchor Project

Project Description

The California Department of Transportation (Caltrans) is proposing a multi-objective anchor project and rehabilitation of existing asphalt concrete pavement on State Route 4 in Alpine County from post miles 0.0 to 31.7 and State Route 89 at post mile 10.84. The rehabilitation includes overlaying, digging out, and cold-planing pavement, upgrading asphalt concrete dikes and curbs, and constructing shoulder backing. The work would also modify or install the following assets to current standards: culverts, bridge-approaching metal beam guardrails, roadside signs, overhead sign structures, and maintenance vehicle pullouts.

Project Benefits


The purpose of this multi-objective project is to improve the pavement condition, culvert drainage systems, visibility of the roadside signs, and roadside safety devices for maintenance workers on State Routes 4 and 89 within the project limits.


The project is needed to preserve and extend the service life of the existing pavement within the project limits. The pavement has minor surface cracks, settlement, and crumbled edges. The project would also fix the deteriorating culvert drainage systems, update nonstandard guardrail systems and nonstandard ground-mounted road signs, and provide maintenance vehicle pullouts for the safety of maintenance workers.
