DETROIT — Mayor Mike Duggan wants to invest $125 million to help revitalize commercial business corridors in Detroit neighborhoods to make them more attractive and pedestrian-friendly.

Duggan said Thursday he will ask the City Council to approve the sale of bonds for the plan.

About $80 million would be spent on infrastructure improvements along Livernois-McNichols, West Vernor, East Warren and other key commercial corridors. Corridor improvements would include landscaping, reconfiguring traffic lanes to add bike lanes, and improved street parking.

The other $45 million would complement existing funds to improve 300 miles of city roads and fix broken sidewalks.

The bonds would be paid back through increased revenues from state gas taxes and vehicle registration fees.

The city says Detroit residents spend about $2.6 billion each year in surrounding communities.
