WGI is nearing the final stages of design for this new roundabout in northeast Tampa. This intersection at Highwoods Preserve Parkway and Highwoods Palm Way experiences heavy congestion during peak-hour traffic and has a nonstandard unsignalized northbound dual-left turn. Converting this intersection into a roundabout will improve traffic operations and efficiency at all times of the day.

Challenges:

• Northbound dual-left turn lane at an unsignalized intersection creates confusion and congestion for drivers
• An unsignalized crosswalk on the northern leg of the intersection lacks median pedestrian refuge and requires pedestrians to cross the entire roadway in one movement
• Constrained right-of-way for the geometric improvements

Solutions:

• The roundabout design provides a safe and efficient dual-left turn movement, while also alleviating AM peak-hour congestion
• The roundabout design allows for shorter pedestrian crossings across Highwoods Preserve Parkway, which provides for safer pedestrian connectivity through the intersection
• Minor design modifications, such as a sidewalk adjacent to the curb, were included to mitigate right-of-way impacts
• WGI employed operational analysis and scenario planning to create a design that will work under multi-modal growth scenarios
