As part of the design-build Monroe Bypass Constructors team, KCI is providing structural design and construction inspection services for the NCTA’s second operational toll facility. At 20 miles in length, the Monroe Bypass Connector will be a full electronic toll facility that extends from I-485 in Charlotte to existing US 74 west of Marshville and includes nine interchanges and 37 bridges. The of existing US 74 serves as an important commercial corridor for Union and Mecklenburg County residents and businesses, with many retail, commercial, and employment centers having direct access to and from the highway. The Monroe Bypass Connector will improve mobility and capacity within the project study area by providing a facility for the US 74 corridor that allows for high-speed regional travel consistent with the designations of the North Carolina Strategic Highway Corridor program and the North Carolina Intrastate System, while maintaining access to properties along existing US 74.
Our team’s proposed approach included the design of several interchanges and ramps to reduce construction, right-of-way costs, and relocations and safety improvements.

KCI designed 17 bridges, including six with dual structures, at 11 sites. Along the one-mile section existing US 74 on the west end, the project consists of an elevated six-lane divided, controlled access toll road with two-lane frontage roads located at or near existing grade along each side of the mainline. The remaining portion consists of a four-lane divided, controlled access toll road with a 46-foot median on new location. The western and eastern ends were designed to meet 60-mph design speeds, while the remaining section meets a 70-mph design speed for a rolling urban freeway. The project was designed to provide a partial interchange at its western end with existing US 74 and full movement interchanges with Indian Trail-Fairview Road, Unionville-Indian Trail Road, Rocky River Road, US 601, NC 200 and Austin Chaney Road.
