Project Description

Financial Project Numbers: 428954-1
Project Limits: Northbound I-75 from I-4 to the Tampa Bypass Canal
Project Length: 2 miles
Estimated Construction Cost: $18 million
Contractor: SEMA Construction, Inc.
Construction Start Date: September 12, 2016

About this Project
The Florida Department of Transportation's contractor is reconstructing the entrance ramps from eastbound and westbound I-4 onto northbound I-75. The project will join the two ramps into one two-lane ramp that will be separated from the mainline travel lanes until merging into a single lane and entering I-75 on a new, long auxiliary lane.

This new entrance ramp alignment will eliminate one merge point onto I-75, increase the acceleration distance for vehicles merging onto northbound I-75, and increase safety in the interchange area. The improvements will extend north on I-75 to the Tampa Bypass Canal, which is over 1.5 miles north of I-4.

Traffic Flow
The construction phasing is designed so that all existing lanes of traffic will be open on I-75 during peak traffic hours.

Night Work
In order to maintain the construction schedule and to minimize the impact to the traveling public, lane closures are planned for nighttime hours.

Lane Closure Hours:
9:00 p.m. to 6:00 a.m.
