Business Loop I-75 - Pontiac

Business Loop I-75 arcs west from I-75 to the city of Pontiac along a 10.27 mile long route (Bessert, 2026). The route travels a freeway west from a directional T interchange (Exit 75) to Square Lake Road and U.S. 24 Business. Turning north, Business Loop I-75/U.S. 24 Business overlap along Woodward Avenue to Downtown where they separate into a one way couplet encircling the central business district. Perry Street branches northeast from the Downtown loop to become Lapeer Street at the Auburn Hills city line. Lapeer Road passes under I-75 without direct access before meeting a trumpet interchange and access road leading Business Loop I-75 back to the freeway at Exit 81.
