Tamiami Trail Restoration
The Project:
In 2005, The U.S. Army Corps of Engineers devised a plan to erect an
Everglades Skyway - an 11-mile bridge to replace part of the road just west
of Miami. But, Congress eventually allocated enough funds to construct a
one-mile bridge in 2008. After the preconstruction and design phase of the
one-mile bridge plan was complete, an $81 million contract was approved in
2008 and groundbreaking took place in December 2009.

In addition to the bridge construction, plans are being evaluated for an
additional series of bridges and/or elevations of the Tamiami Trail to
facilitate additional water flow. This effort will be critical to the
recovery of the Everglades and Florida Bay. Everglades Foundation scientists
see the one-mile bridge as a critical first step to improve water flow
through the barrier. "Our scientists will be monitoring the impact of
improved water flow along Tamiami Trail. One area of particular interest is
the effect of improved water flow on highly toxic mercury levels," says Van
Lent. The fluctuating mercury levels will help scientists understand how the
introduction of more fresh water will affect the ecosystem. That will help
government agencies make enlightened decisions on restoration. "If we do
restoration, we don't want to do anything with unintended consequences,"
adds Van Lent.

The Future
The U.S. Department of the Interior's National Park Service released a draft
Environmental Impact Statement (EIS) in May 2010 that recommends an
additional 5.5 miles of bridging on Tamiami Trail in addition to the one
mile of bridging currently under construction to restore natural water flows
to the Everglades.  The new bridging would create an opportunity to restore
up to 100 percent of the historic volume and distribution of water that used
to flow southward into Northeast Shark River Slough before the Trail was
constructed. If completed, the additional bridging would eliminate the
hydrologic constraints throughout much of the southern Everglades, including
the Water Conservation Areas and Everglades National Park. For more

The Tamiami Trail bridge is part of a larger effort to "de-compartmentalize"
the Everglades to restore the natural flow of the River of Grass. While the
Everglades will never be restored to its once pristine state, projects such
as the Tamiami Trail bridge are part of a solution to allow the Everglades
to benefit from free-flowing water which could revitalize plant and animal
populations and sustain the water supply for South Florida's human
inhabitants. "We're on a track to demonstrating really tangible results in
the saga of Everglades restoration," says Van Lent. "We're putting a big
hole in the dam."
