I-4 at Polk County Line Road Design-Build

WGI was the engineer of record for this project which widened the I-4 eastbound off-ramp to provide for 700-foot dual right turn lanes with tapers and a single left turn lane. The single-lane eastbound on-ramp was maintained. County Line Road was widened to provide 260-foot southbound dual left turn lanes onto South Frontage Road. South Frontage Road was widened to receive the dual lefts and tapered back to a two way roadway. Separate westbound right turn lane and a thru-left turn lane were provided on South Frontage Road. Sidewalk, curb and gutter were replaced as necessary. New traffic signals and pedestrian features were installed on County Line Road at the off-ramp and at South Frontage Road. Signage for the I-4 Interchange was updated per the 2009 MUTCD. The corridor was milled and resurfaced and thermoplastic pavement markings were installed. All work was conducted within FDOT right-of-way.
