I-95 at Becker Road System Interchange Reevaluation Study


I-95 at Becker Road System Interchange Reevaluation Study

Client: City of Port St. Lucie

Location: Port St. Lucie, Florida

Construction Value: $893,010

Completion Date: 2008

Description:

American provided planning and design revision services for 1.3 miles of Becker Road including modifications to the I-95 interchange. Services provided on this project included a revised System Interchange Justification Report (SIJR) for modifications to the interchange. The new configuration will have dual left-turn lanes, three through lanes and one right-turn lane. The current design configuration only provides for a single left-turn lane, three thru lanes and dual right-turn lane. The reevaluation study utilized CORSIM software for the analysis. The revised design plans included roadway, structures, traffic, drainage, lighting, signalization and signing and marking.

After this interchange was under construction, development to the west was modified to include a regional mall and preliminary modeling indicated that the interchange under construction would be unable to handle the anticipated traffic generated by the regional mall. The designated limits of the controlled right-of-way would also prohibit future access to and from the mall. American prepared a revised SIJR that identified necessary modifications that would be required in the future and how they would impact the mainline. American also evaluated the limits of the controlled right-of-way, prepared justification to modify the western limit and received approval from FDOT.

Conceptual plans were developed for these improvements and final plans were developed to modify Becker Road construction to accommodate future improvements to the on and off ramps. American was responsible for the planning, design and construction services for these improvements. This included responsibility for obtaining all Federal Highway Administration, Florida Department of Transportation and South Florida Water Management District approvals.
