EMERGENCY RESTORATION OF HISTORIC MAIN STREET BRIDGE ELEMENTS
Duval County, FL
Listed on the National Register of Historic Places, downtown Jacksonville’s Main Street Bridge required emergency replacement of the concrete structure carrying Main Street over Hogan’s Creek. The Main Street Bridge Culvert is a historic structure associated with Henry J. Klutho, a notable Jacksonville architect who designed many of its significant buildings and structures. The early 20th-century site has character-defining features designed by Klutho, such as obelisks, cartouches, medallions, and urns on the walls of the bridge culvert.
The necessary utility relocation required multiple negotiations for four critical utility facilities. Challenges for the Department and utility owners were magnified due to the condensed project schedule and the layers of trolley tracks and brick pavers uncovered during construction. During excavation of the site, a large, previously unknown 30’ x 6’ x 6’ void was discovered under the road and further jeopardized an existing AT&T manhole. After researching and analyzing several options, AT&T decided a specialty contractor was needed to perform the work. Through innovation, proactive efforts, and construction phase coordination, all factors were mitigated without impacting the construction schedule.
