Project Description

The purpose of Caltrans' first design-build project in the state is to rehabilitate Highway 99 from South Gateway Overcrossing to Avenue 16 Overcrossing in the Northbound and Southbound direction. The total length of the project is approximately 3.6 miles.

This project will rehabilitate identified sections along four miles of State Route 99 by reconstructing PCC lanes and asphalt concrete shoulders. Reconstruction of the # 2 (truck) lanes with Continuously Reinforced Concrete Pavement (CRCP) will provide longer service life to these sections of roadway. Guardrails, lighting, signage and drainage located within the project limits will be upgraded or repaired as needed.

The scope of the project includes highway reconstruction, guard-railing and signage upgrades, electrical modifications as well as a minor storm drain improvements. This project will be constructed in four different stages. Each stage will include traffic detours and ramp closures that will temporarily impact public travel. The project estimated value is $37 Million from the State Highway Operations and Protection Program (SHOPP)

The Commuter Alerts will identify the current impacts to public travel during the different stages of construction:

• Night Time and Day Time On/Off Ramp Closures

• Extended Ramp Closures for Hwy 145 Interchange, 2nd Street and 4th Street

• Reduced Traffic Speeds on Highway 99 During Stages 2, 3 & 4

• Traffic Delays During Temporary Lane Closures

• Business Impacts during ramp closures- Modify delivery routes

• Busses(school, city) impacts during daytime closures-Detour Access Provided

• Impacts to emergency services during closures-Detours provided
