The Monroe Expressway was initially proposed as two separate projects: the
Monroe Bypass and
Monroe Connector. The original environmental planning process for the Monroe Bypass concluded in 1997, including a preferred alternative. The road would have begun near the intersection of US 74 and Rocky River Road, running northeast to the current location of the Monroe Expressway near Secrest Short Cut Road. From here, it would have followed the current alignment of the road to its terminus at US 74 between Wingate and Marshville. The project was divided into three sections: Section A from US 74 (western terminus) to US 601, Section B from US 601 to Richardson Creek, and Section C from Richardson Creek to US 74 (eastern terminus). After a public meeting, planning for Section A was suspended and the Monroe Connector was proposed to directly connect the bypass to I-485. Planning for the Monroe Connector began in 1999, with a draft environmental impact statement (EIS) issued on October 17, 2003. Among the alternatives considered were simply upgrading US 74 to a freeway or building the road on a new alignment, as well as various locations to connect to I-485, including the existing interchange with US 74. In 2005, the
North Carolina Turnpike Authority considered building the Connector as a toll road at the request of the Mecklenburg–Union Metropolitan Planning Organization (MUMPO). Meanwhile, NCDOT continued to develop the Monroe Bypass project separately. With the original environmental studies for the Monroe Bypass almost 10 years old, the
Federal Highway Administration required NCDOT to reevaluate the documents before starting construction. All three sections would need to be included in the reevaluation in order for the road to function as a stand-alone bypass. However, MUMPO's 2030 Long Range Transportation Plan (LRTP) omitted Section A in favor of the Monroe Connector. With inclusion in the LRTP required for FHWA approval, and the Monroe Connector and Sections B and C of the Monroe Bypass requiring the other in order to function as a single road, the reevaluation was discontinued so that the two projects could be combined. The final EIS for the combined project issued in August 2010, including the selected alternative of a controlled-access toll road. By 2015, the proposed toll road was officially renamed the Monroe Expressway. Construction on the Monroe Expressway began in May 2015, with the road finally opening on November 27, 2018. ==Tolls==
