The Middlesex Corporation provided the Construction Management and General Contractor (CM/GC) services for the pre-construction and construction of the repair, alignment and strengthening of the CSXT South Fork New River Bridge, No. SX1013.8 in Fort Lauderdale, Florida.

The bridge is part of the South Florida Rail Corridor right-of-way, which is owned by the Florida Department of Transportation (FDOT) and maintained and operated by the South Florida Regional Transportation Authority (SFRTA). The CSXT freight railroad is the main user of the bridge. The bridge consists of four spans for a total length of 265′-11⁄2″, it includes a 98′-0″ Rolling Lift Bascule span over the South Fork of the New River. The overall width of the movable span is 22′-6″. Pre-construction services included the survey of existing conditions, constructability reviews, material availability analysis, and cost estimates. Construction services included the replacement of existing pinion shaft couplings, functional checkout/testing, 60-day operational period, painting of bridge machinery, and safety improvements.

Unique Challenges

To accommodate and reduce impacts to all the stakeholders, Middlesex developed an innovative solution for replacing the existing bridge couplings (east and west) by operating the bridge from one drive system (east or west) at a time.
Stakeholders to agree to performing the repairs during the day with the bridge in the open position to accommodate marine traffic and closing the bridge at night to accommodate rail traffic.
Extensive communications with all stakeholders and working 12 hours a day 7 days a week to meet the agreed upon schedule to complete the repairs.
