Until late 2017, access to J.T.B eastbound from I-95 southbound was handled through a traffic-signaled intersection that was located near the highway's western end. This configuration created significant congestion during rush-hours, causing traffic to back-up onto I-95. To alleviate this situation, a flyover was constructed during the mid-2010s from I-95 southbound to J.T.B eastbound, along with other improvements to the I-95/J.T.B/Belfort Road/Salisbury Road interchanges. Under this new configuration, the signaled intersection remained in place but is now only used to provide access from I-95 to the Belfort/Salisbury/Southpoint commercial area since the new flyover merges into J.T.B eastbound past the existing off-ramps in the Belfort/Salisbury interchange.
