East Selmon Expressway Slip Ramps
The Middlesex Corporation constructed slip ramps from west of the I-4 Connector to east of N. 34th Street, and from east of US 301 to I-75 in Hillsborough County.
One new egress ramp and two new ingress ramps were constructed. New ramp additions were connected by widening on the existing alignment. Existing guardrail and barrier wall were removed and a new barrier wall was placed to provide separation between slip ramp and local lanes. Middlesex also removed and reconstructed two overhead sign span assemblies, milled and resurfaced the existing lanes, and installed wrong-way driving gates and associated infrastructure.
