DETROIT — With four counties expected to weigh a tax millage to pay for public transportation in November, the Regional Transit Authority of Southeast Michigan (RTA) unveiled its plan, which includes more than 70 bus rapid transit (BRT) stops on three corridors, a transit connection to Detroit Metro Airport, and a commuter rail line connecting Detroit to Ann Arbor, Mich., the Detroit Free Press reports.

Initial cost estimates provided by the RTA say the three-route BRT lines would each cost about $20 million per year to operate and $4 million to $9 million per mile to build, depending on the final design. The rail line, which would use existing infrastructure but require some upgrades, would cost $8 million to $12 million per year to operate.

The RTA is holding a string of open houses in advance of the crucial November vote. For the full story, click here.
