Iowa's MRT will incorporate already existing or planned off-road bike trails, including the Heritage Trail in Dubuque, the RiverWay Trails in the Quad Cities, and many others. Only an additional nine miles of new off-road trails will need to be constructed where roadways were found to be unsuitable for bicycle lanes.
The MRT's off-road bike trails will be 10 feet wide to accommodate both bicyclists and pedestrians. The total estimated cost of paving new bicycle trails with asphalt is $920,000.
