This project features the final phase of the ultimate 408/417 Interchange and includes 4 ramp reconfigurations, 2 new flyover bridges (design by others), MOT, conventional lighting, ITS upgrades, overhead sign structures, MSE walls, and 1 new storm water pond.

Colonial Pedestrian Overpass

Project consists of the design of a signature pedestrian overpass and associated approach ramps to span over Colonial Drive (SR  50) and the Central Florida Commuter Rail (SunRail) to provide bicycle and pedestrian connectivity between the Gertrude’s Walk and Dinky Line segments of the Orlando Urban Trail. Project included a stairway for direct connection to Colonial Drive and ADA ramps for connections to Concord Ave, Colonial Ave and Orange Ave. The design provided a street plaza area with amenities, pedestrian safety lighting and aesthetic lighting for the main 80’ tall pylon and the ramp piers.

SR 44 Roundabout at Grand Avenue

Horizon was the lead design firm for the this low - bid (Design Build) project that includes design and construction of a roundabout on SR 44 at Grand Avenue in Volusia County. Improvements include the design and construction of roadway, channelization islands, drainage system, sidewalks, signing and pavement markings, lighting and landscaping.

SR 35 (Baseline Rd)
