The northern terminus of the line is at Burns Commons (Ogden Avenue at Prospect Avenue).
From there, the line follows Ogden Avenue in both directions to Jackson Street and then Jackson Street to Kilbourn Avenue.
After a short segment of two-way running on E. Kilbourn Avenue, the route connects with N. Broadway (southbound running) and N. Milwaukee Street (northbound running).
Two-way running resumes at E. St. Paul Avenue.
After crossing the Milwaukee River, the line then follows W. St. Paul Avenue in both directions to N. 4th Street, terminating at the Milwaukee Intermodal Station.
Earlier plans to begin the line at Ogden Avenue and Farwell Avenue, and to run northbound on Van Buren Street and only southbound on Jackson Street were dropped to reduce utility relocation costs.

The first line, designated the M-Line, from Burns Commons to Milwaukee Intermodal Station, is 2.1 mi (3.4 km) long.
The route follows separate streets in opposing directions for around 0.575 miles (925 m) of its length.

In October 2015, the project received a federal grant which will cover approximately half the cost of a spur to the lakefront.
This spur, or branch, to N. Lincoln Memorial Dr. will go via E. Michigan St. and E. Clybourn Street, and is expected to commence service in late 2020.
By June 2018, it had already been fully constructed except for its outermost section, where delays to the start of work on the proposed "Couture" high-rise development prevented construction of the streetcar line.
The branch is planned to be served by a route, designated as the L-Line, which would also use the tracks of the M-Line along Milwaukee Street and Broadway to make a loop around downtown.

The system's car house, its storage and maintenance facility, is on Vel R. Phillips Avenue (4th Street), under an elevated section of the I-794 freeway.

Of the 2.1-mile (3.4 km) length of the first line, 3,300 feet (1 km) is not equipped with overhead wires.
The streetcars cover these sections along Kilbourn Avenue and Jackson Street powered only by their batteries.
A portion of the future Lakefront Line will also be unwired.

The City of Milwaukee has applied for a TIGER Grant to gain federal funds to fund 50% of the system's extension up 4th St. towards the new Fiserv Forum and the Bronzeville neighborhood.
