Overview
Project background
Bristol Street is one of Costa Mesa's primary arterials. LDC provided the engineering and surveying needed to rehabilitate 2.5 miles of pavement, drainage and frontage — a public-works project executed under traffic on one of the city's busiest corridors.
The Challenge
What this project demanded
Rehabilitating 2.5 miles of arterial without shutting it down — keeping commuters, transit and businesses moving while crews worked lane by lane.
Our Approach
How LDC delivered
- Surveyed the corridor at high resolution so design tied cleanly to existing curb, gutter and drainage.
- Designed in segments that matched the City's preferred traffic-control phasing.
- Built in ADA upgrades at every curb return touched by the work.
Outcome
What got built
2.5 miles of rebuilt arterial that gave Costa Mesa a smoother, safer Bristol Street with modern ADA compliance.
