|Work Type||interchange improvement|
|Limits||Northbound I-75 from I-4 to the Tampa Bypass Canal|
|Project Start||September 12, 2016|
|Construction Cost||$18 million|
|Estimated Completion||Summer 2018|
|Contractor||Sema Construction, Inc.|
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.
The construction phasing is designed so that all existing lanes of traffic will be open on I-75 during peak traffic hours.
In order to maintain the construction schedule and to minimize the impact to the traveling public, lane closures are planned for nighttime hours.
