TEMPORARY GANTRY CALCULATIONS

HOT Lanes Project (I-77)

SUMMARY

The behavior of the structural system of the support structure for system was evaluated using the calculation and structural analysis software SAP2000.

Charlotte-based I-77 Mobility Partners is financing, developing, designing, constructing, operating, and maintaining the 26-mile project. NCDOT retains ownership of the roadway and helps ensure I-77 Mobility Partners adheres to the standards of their contractual partnership. Construction, managed by Sugar Creek Construction, began in 2015. I-77 Express opened in November 2019.

By converting the current High Occupancy Vehicle (HOV) lanes to Express Lanes, more vehicles will travel more quickly through the north corridor. During each trip, motorists will be able to decide if they want to use the express lanes, the general-purpose lanes or a combination of both to allow for a more efficient drive.

I-77 Mobility Partners asked AZIERTA to assist in the structural design study for the Temporary Gantry Structure. The basic scope of the Project consists of the evaluation of new scenarios for the support structure for the proposed Temporary Gantry Structure, shared by I-77 Mobility Partners to AZIERTA.
