Tamiami Trail Modifications

Project Description

The Tamiami Trail roadway is owned by the Florida Department of Transportation (FDOT) but runs through the Everglades National Park (ENP). This TIGER Project is part of a larger Everglades restoration effort known as the Modified Water Deliveries Project (MWDP), a joint undertaking of the Army Corps of Engineers, the Department of the Interior (DOI), the National Park Service (NPS), and FDOT. The purpose of the larger project is to enhance and restore the ecological values and natural hydrologic conditions in the ENP. This is reflected in the 2009 Omnibus Appropriations Act (Act) (P.L. 111-008, March 11, 2009), where the DOI and the NPS was directed "to immediately evaluate the feasibility of additional bridge length, beyond that to be constructed pursuant to the MWD Project (16 U.S.C. SS 410r-S), including a continuous bridge, or additional bridges or some combination thereof, for the Tamiami Trail (U.S. Highway 41) to restore more natural water flow to Everglades National Park and Florida Bay and for the purpose of restoring habitat within the Park and the ecological connectivity between the Park and the Water Conservation Areas." (Tamiami Trail Modifications: Next Steps Project, cited herein as TTMP). The environmental evaluation for the TTMP resulted in a NPS Final Environmental Impact Statement (FEIS) followed by a NPS Record of Decision (ROD) issued on February 11, 2011. The purpose and need for the project is environmental restoration and improved hydraulic connectivity. On September 12, 2014, USDOT announced that FDOT would receive a $20 million TIGER VI grant for this project. FHWA will have stewardship and oversight responsibilities for the TIGER Grant and other Federal Lands Transportation Program (FLTP) funds.

The first phase of the TTMP includes construction of numerous bridges and related work within the 10.7 mile length of the Tamiami Trail(U.S. Highway 41) located immediately adjacent to the north boundary of the ENP, including (west to east); 2.3 miles of bridging and 0.9 mile of roadway transitions, maintenance of access near Everglades Safari Park(ESP), Water Conservation Areas future removal of the access road to the Lincoln Financial Media radio tower facility (Lincoln Financial), the removal of the roadway section north of the bridge opening, as well as construction and operation of a stormwater management system along the Tamiami Trail roadway. The bridges will provide two 12-foot-wide travel lanes with 10-foot shoulders - the roadway will have a 10-foot shoulder west bound and an 8-foot paved shoulder and 3.5-foot shoulder gutter east bound, guardrail and fill slope. After completion of bridge construction, the unneeded portions of the Tamiami Trail roadway will be removed and the remaining (existing) road embankment will be slightly raised to a roadway surface elevation of 13.13 feet.

Environmental Documentation

The NPS has completed a Final Environmental Impact Statement (FEIS) and issued a Record of Decision (ROD) for this project. The Eastern Federal Lands Highway Division (EFLHD) of FHWA has adopted the NPS FEIS and on February 9, 2015 issued a ROD based on the adopted FEIS and supplemental information. In February of 2014 a public information meeting regarding FHWA’s intent to adopt the NPS FEIS was conducted in the project area. The Congressional Consolidated Appropriation Act of 2014 directed that the project's requirements regarding US Department of Transportation Section 4(f) had been met.
