I-5786, I-95 Resurfacing

NCDOT Project I-5786 is a pavement rehabilitation project along I-95 from just south of SR 1001 (Lizzie Mill Rd.) to the Johnston/ Wilson County Line just north of NC 22 (7.3 miles). The project was performed under an accelerated project schedule.

The project consisted of installing concrete median barrier, overlaying the existing I-95 pavement, performing concrete slab replacement and the replacement of Bridge Nos. 108, 111, and 117 over I-95. The replacement of Bridge Nos. 108 (SR 1001, Lizzie Mill Rd.) and 111 (SR 2141, Bizzell Grove Church Rd.) required the use of rock plating, the re-alignment of SR 2392 (Seafood House Rd.) and SR 2402 (Woodside Rd.,) and the installation of several driveways to allow traffic to be maintained during construction.

The replacement of Bridge No. 117 on SR 2399 (Truckstop Rd.) required the bridge be constructed utilizing phased construction to minimize right of way impacts, as well as for the maintenance of traffic through the interchange. The new structures will accommodate the proposed future widening of I-95 to its ultimate 8-lane typical section. NCDOT Project I-5786 also required the coordination between Wetherill Engineering, NCDOT (project I-3318BB), and Stantec Consulting (project B-4937).

The existing drainage was evaluated and median drainage needs for the increased impervious area was accommodated, resulting from paved median and barrier. It also included the evaluation and addressing of existing pipes for capacity issues as evident by calculations and visual outlet inspections. WEI worked with NCDOT to identify and correct potential conflicts with the future widening of I-95 where it was possible.

Wetherill Engineering was selected to perform final engineering designs for the proposed project. WEI’s scope of service includes roadway design, hydraulic design, erosion control, traffic control plans, pavement marking plans, structure design, utility construction plans and utility coordination. Our construct was also supplemented to perform singing designs for Y-lines, evaluate existing signing and signing design for outdated signs along the I-95 project corridor
