Jefferson Avenue is a scenic road along the eastern part of the Detroit metropolitan area in the U.S. state of Michigan. It travels alongside Lake Erie, the Detroit River, and Lake Saint Clair. This road also provides access to many recreational facilities in the area. West Jefferson Avenue is primarily a commercial, while the East Jefferson Avenue contains a historic residential district.
Jefferson is one of five major avenues (along with Woodward, Michigan, Grand River, and Gratiot) planned by Judge Augustus Woodward in 1805 that extend from downtown Detroit in differing directions. First surveyed in 1807, it was named Main Street. It was later renamed Jefferson Avenue after U.S. President Thomas Jefferson, who was a friend of Woodward.  Jefferson Avenue was planned to extend due east of downtown, parallel to the Detroit River. Later additions to the road have extended it west of downtown as well, where it continues to travel near the waterfront through the Downriver area.
This road originates in the City of Detroit. Jefferson passes under Cobo Convention Center, but such structures as 150 West Jefferson and the UAW-Ford National Programs Center are located upon it as it rises to ground level there. It then passes through much of eastern Detroit and then the Grosse Pointe communities, St. Clair Shores, and Harrison Township, among others. It also serves as the backbone of the rich neighborhoods of the Grosse Pointe communities, skirting the eastern portion of Detroit. Westward, Jefferson Avenue passes under the Cobo Center and by Joe Louis Arena, then it passes through the Downriver communities, Brownstown Township and Berlin Township, intersecting with roads leading to bridges to Grosse Ile (Grosse Ile Parkway in Trenton leading up to Wayne County Bridge and Bridge Road in Riverview leading up to Grosse Ile Toll Bridge). The Trenton Channel Power Plant and Elizabeth Park are located along Jefferson Avenue in Trenton.
Although the road is continuous with Jefferson Avenue to the north and south, the name changes in Wyandotte to Biddle Avenue; similarly, in Grosse Pointe Farms and Grosse Pointe Shores, the name changes to Lake Shore Drive; the name also changes to U.S. Turnpike Road in Berlin Charter Township. A gap occurs at the former Selfridge Air Force Base, now a golf course and the Selfridge Air National Guard Base.
Jefferson Avenue's north end is at 23 Mile Road, near the boundary between Chesterfield Township and New Baltimore; the southern end of this northern portion is in Berlin Township at the intersection with Dixie Highway and Strong Road.
There is a one block gap in Jefferson Avenue on Detroit's southwest side, between Clark and Scotten Sreets. In downtown Detroit, the southern end of M-10 is routed on Jefferson to the corner of Randolph St./M-3. From the corner of Randolph to the southern end of I-375 between Beaubien and St. Antoine streets, Jefferson is the extremely short, 0.015 mile-long, unsigned BS I-375.
