Nocatee Bridges (Phase I-III)

The Parc Group

View Details

Through ETM’s involvement with the 15,000 acre Nocatee Development of Regional Impact as the District Engineer, ETM was responsible for providing CEI services for multiple bridge structures including interchanges, low level bridge wetland crossings and the construction of a Category 2 curved Steel Bridge structure.  

Nocatee Parkway

Nocatee Parkway is a 7 mile, 4 lane limited access facility, which runs from Philips Highway (US 1) through Nocatee and out to the beaches. The new $150 Million highway was designed to provide the community with easy access to Philips Highway as well as a convenient way to get from one side of Nocatee to the other.  

 

Single Point Urban Interchange (SPUI) – Nocatee Parkway at Crosswater Parkway

Part of constructing both Nocatee and Crosswater Parkways included the need to create an interchange that connected the two collector roadways.  Along with designing the interchange itself and the drainage, utilities, bridges, lighting and landscape that go with it, ETM coordinated the Single Point Urban Interchange construction with St. Johns County, FDOT, utility companies, and adjacent landowners.   This structure included twin 276’ single span Steel I-Beam girder structures with prestressed pile foundations, stay-in-place decking, cross frame connection plates and bearing and jacking stiffeners.  ETM was responsible for implementing/inspection utilizing "FDOT's turn of the nut specifications" for bolting and coordinating the MSE wall strapping with back wall end bent construction.

 

Crossroad Bridge, Valley Ridge and Durbin Creek Bridge Structures 

In support of the Nocatee Parkway initial construction (Phase I) and subsequent parkway extension (Phase III), ETM was responsible for providing CEI services for multiple concrete bridge structures identified as follows:  

  • Crossroad Bridges were twin concrete structures with a medium profile and 75’ single span utilizing Type III AASHTO Girder structures on a super elevated curve with a continuous CIP deck utilizing stay-in-place decking, pre-stressed concrete pile foundations and installation of spiral MSE wall.  
  • The Valley Ridge interchange bridges included twin AASHTO concrete girder double span structures at a fully functioning interchange connecting Nocatee Parkway with Valley Ridge Boulevard.
  • The Durbin Creek Bridge structure was an approximately 800 linear foot low level bridge crossing of Durbin Creek that required phased construction due to limited work space availability within and adjacent to environmentally sensitive wetlands.

 

Nocatee Parkway/US-1 Flyover

ETM provided CEI services and contract administration duties for this Category II steel plate girder/AASHTO beam bridge structure. This project required intricate MOT phasing of the bridge pier foundation construction within the US-1 right of way, construction of steel girders and the use of staging towers. Management and engineering services included the review of contractor bracing plans, erection plans and inspection of bridge coatings of steel girders.
