The American Council of Engineering Companies of Florida (ACEC-FL) recognized Hanson for its work on the State Road A1A/San Marco intersection improvements in St. Augustine, Florida.
Hanson received an Outstanding Special Project Award as part of the organization’s Outstanding Project Awards. The awards recognize member firms’ achievements in Florida Department of Transportation (FDOT) studies and projects. Winners were recognized at the ACEC-FL Transportation Conference in Orlando.
The State Road A1A/San Marco intersection is a gateway entrance to St. Augustine’s historic downtown and an important connection to U.S. 1, SR A1A, as well as the area’s beaches, neighborhoods, businesses and the Florida School for the Deaf and the Blind (FSDB). This intersection sees a high volume of traffic, including sightseeing trolleys, semitrucks and vehicles pulling boat trailers.
U.S. 1, San Carlos Avenue and May Street all converged at San Marco Avenue to form two adjacent signalized intersections. This area often became a bottleneck, with traffic backing up several hundred yards in all directions, including onto a nearby bridge. Besides the mounting traffic congestion and frustration caused by these intersections, the city of St. Augustine and FDOT’s District Two were focused on the safety of motorists, pedestrians and bicyclists traveling through this busy, challenging juncture.
Dynamic, fluid project demands innovative design solutions
During this project, Hanson worked with FDOT to design the realignment of two problematic intersections to a single quadrant offset T-intersection. This was the first time this type of intersection was proposed, designed and constructed.
This project also involved numerous design elements. These included lighting, which was brought up to new intersection standards, 10 new signal mast arms designed to meet hurricane-force winds, the first High-intensity Activated crossWalK (HAWK) crossing in northeast Florida, redundant traffic signals, visual and audible pedestrian signals and the signage and striping to address the unique lane configurations.
The addition of dedicated right and left turn lanes, median modifications, synchronized traffic signals, sidewalks, shared bicycle lanes and HAWK pedestrian signals improved traffic flow and safety for pedestrians and bicyclists.
This concept improved the safety and usability of the intersection and changed the way FDOT’s District Two approached future intersection design projects with innovative ways to improve intersections, traffic phasing and signalization.
“This project showcases the positive outcomes that can occur when engineering and transportation professionals listen to the needs of their clients and communities, engage with them and work together to create a solution that improves safety, travel and quality of life,” said Hanson’s project manager, Chantal Bowen.
