David Bogan (I-10 Escambia Bay) Bridge

The I-10 Escambia Bay Bridge in Pensacola, FL was rebuilt under a fast-track schedule after it was heavily damaged during a series of hurricanes in 2004. WSP USA designed the new bridge and provided support services during construction.

For nearly two years, motorists on the busy interstate route had faced lane closures, low speed limits, and vehicle size and weight restrictions that hindered mobility, tourism, and commercial traffic. Replacing the bridge and opening it to traffic was one of the highest priorities of the Florida Department of Transportation (FDOT), the Federal Highway Administration, and the Governor of Florida.

FDOT rapidly launched a $243 million design-build contract for replacement of the bridge and, WSP began design. The new girders are Florida Bulb-T beams, which are longer and lighter than the original girders, thus requiring fewer piers and saving money and construction time. The precast concrete bridge segments are as uniform as possible, which accelerated work at the casting yard and the construction site.

Four named storms impacted bridge construction, forcing FDOT to adjust the completion date for the eastbound structure.

A key improvement was increasing the minimum clearance to 25 feet above the usual water level to better resist storm surges. Each structure consists of three 12-foot travel lanes and 10-foot inside and outside shoulders. The increased vertical clearance accommodates larger ships and an interlocking system between substructure and superstructure enhances bridge strength.

Awards included the 2008 American Road & Transportation Builders Association (ARTBA) Globe Award for Environmental Excellence, Honorable Mention for sediment control and recycling programs; the 2007 PCI Design Award, Best Bridge with spans greater than 150 feet (co-winner with Arthur Ravenel Jr. Bridge); the 2007 FHWA Excellence in Utility Relocation and Accommodation Award in Project Management category; and the 2007 Gulf Guardian Award, U.S. Environmental Protection Agency, Gulf of Mexico Program. The project was ranked Number 1 by Roads and Bridges magazine in its 2007 Top Ten Bridges list.
