Along with widening the roadway, development has concerned important structural enhancements. The S. T. Wooten workforce has constructed 13 bridges to satisfy fashionable engineering requirements. Upgrades embody the substitute of 9 present bridges over I-95, one new bridge over I-95, two new bridges which have changed outdated undersized field culverts, and lastly a brand new single bridge alongside I-95 changing two older bridges. On prime of the bridge work the undertaking required, three noise partitions have been constructed and development of a fourth noise added to the undertaking scope is about to start very quickly.

Overcoming obstacles
Scale and complexity have introduced distinctive challenges for the I-95 job, notably the want to take care of site visitors circulate alongside one of many nation’s busiest highways. Not like different development websites, site visitors volumes stay constantly excessive all through the day, with heavy vehicles producing noise and wind that complicate work zone situations.
To attenuate disruptions, phased development and evening shifts have been essential. Throughout early phases, site visitors was routed via temporarily-widened inside lanes, whereas the newly designed outer lanes have been constructed. Climate delays, particularly within the rain-prone Sandhills area, have additionally prompted crews to adapt schedules and add shifts to maintain the undertaking on observe.
Perseverance and security

Enhancements to the plan
Whereas the unique scope of the I-95 undertaking is sort of completed, the NCDOT has added new duties and alter orders which have prolonged the deadline for completion. These changes are frequent in large-scale infrastructure initiatives and mirror efforts to refine particulars and make sure the finest outcomes for the general public.
Redesigns for roundabouts at Exits 58, 61 and 65 have been accomplished in 2024, including a brand new roundabout on the southbound Exit 58 ramp.
