Document Description
The California Department of Transportation (known as Caltrans) proposes to address structural deficiencies and improve multimodal travel along State Route 183 (locally known as Merritt Street) through the census-designated town of Castroville in Monterey County from post miles R8.3 to 9.98. The project will rehabilitate the pavement, address essential bridge maintenance needs, and improve multimodal features, including transit stops, sidewalks, driveways, and curb ramps. The project will also install new Intelligent Transportation System features and improve aesthetics, bicycle network continuity, and pedestrian safety. More specifically, the project will: • Rehabilitate, through cold planing and asphalt overlay, the pavement to improve the ride quality and prevent further deterioration. • Address the maintenance needs of the State Route 183/State Route 156 Separation Bridge (Bridge Number: 44-0185) through concrete spall repair and deck and crack sealing to prevent water intrusion into existing cracks. • Improve accessibility under the Americans with Disabilities Act to address deficiencies within the project limits where feasible. • Reconstruct existing and construct new sidewalks, driveway tie-ins, curb ramps, extended curbs, crosswalks, and pedestrian crossing aids to improve access and connectivity for pedestrian users. • Construct bus bays and landing areas, reconstruct existing transit stops, and relocate and combine some transit stops to improve access and connectivity for transit users. • Delineate Class 2 Bike Lanes at select locations to improve access and connectivity for bicycle users. • Extend the queuing and maneuvering area at the existing shared through lane and right-turn lane at northbound State Route 183 (Merritt Street) and the eastbound State Route 156 on-ramp, construct striped side street splitter islands in the Merritt Street median at Salinas Street and Haro Street, and construct curb tapers on both sides of Merritt Street between Crane Street and Preston Street to improve vehicular operation and movement through the project corridor. • Replace existing traffic census stations with upgraded systems and install a closed-circuit television camera system on the traffic signals at the State Route 183 (Merritt Street) interchange with State Route 156 to improve collection and reliability of real-time traffic data for traffic management purposes. • Widen the existing State highway right-of-way and acquire new right-of-way to construct roadway and multimodal access improvements along State Route 183 (Merritt Street). State Route 183 (Merritt Street) is a conventional highway that serves as the “Main Street” through Castroville. The narrow right-of-way in this older, suburban setting makes it necessary to acquire permanent (or fee) right-of-way to complete sidewalk, curb ramp, and minor operational improvements; and to obtain Temporary Construction Easements for transitions or tie-ins on nearby property. Approximately 81 parcels will be impacted.
