Quarry Road Low Water Crossing

Should San Diego County build a bridge that is already Federally funded to provide safer access for residents, pedestrians, bicyclists, and emergency vehicles? Or should it not be built to avoid impacting nearby business' & land owners?

Which Concept do you prefer?

CONCEPT A: Build new bridge to eliminate all road closures due to flooding - realign road to remove sharp curve; requires impacts to adjacent private property by removing and/or relocating access points and buying property; approved for federal funding; estimated construction in 2025

Design Concept for Quarry Road Bridge

CONCEPT B: Drainage improvements to reduce road closures due to flooding - maintains current road alignment; reduces impacts to adjacent private property; partially funded with local funds; estimated construction unknown based on funding availability

CONCEPT C: Improvements to existing gates - maintains current road alignment; continues use of gates to close road during storm events due to flooding; no impacts to adjacent property

 Approx. Traffic Counts:
Weekday: 10,000 vehicles
Weekend day: 40,000 vehicles

Annual Number of Road Closures:

Seeking Public Input

The County of San Diego was seeking public input (from August to November 2021) to address the low water crossing on Quarry Road just east of State Route 125 to provide safe access for residents, pedestrians, bicyclists, and emergency vehicles. Survey data is now being summarizing and the County will then reach back out to the community with the results after internally vetting them. 

The survey is now closed
