Vasco Road Safety Improvements

Project Information

Project Number: 0662-6R4255

Purpose and Need: 
Vasco Road is a major rural arterial that is heavily traveled by commuters and has a history of severe collisions. The project will improve safety on Vasco Road by reducing cross median crashes. These long-term upgrades and improvements will provide substantial safety improvements to the roadway.

Phase 1: 
Construction for Phase 1 improvements was completed in January 2012. Improvements included construction of approximately 1 mile of concrete median barrier, bridge and roadway widening to close a gap in the southbound truck climbing/passing lane. Project funding came from the American Recovery and Reinvestment Act of 2009, federal earmark, Proposition 1B, Measure C/J sales tax, and Gas tax.

Phase 2: 
Phase 2 will continue the concrete median barrier in the northerly direction through the existing 3-lane segment for an approximate length of 1.5 miles. Associated pavement widening, signing, striping, turn pockets, retaining walls, drainage improvements, wildlife mitigation, bridge widening, and barrier end-treatments will be constructed as necessary to accommodate the installation of the median barrier. The project is fully funded with a combination of Regional Measure 3 funds, Gas Tax, and Measure C/J funds. Construction is scheduled to begin in 2021.
