Across 94 pages, Nashville Mayor Freddie O’Connell has laid out a proposal to transform the city’s transportation systems.

The $3.1 billion proposal would establish dedicated funding — raised through a half-cent sales tax increase — to construct new sidewalks and bike lanes, update traffic signals, build safer pedestrian crossings, increase bus service frequency, and, in some areas, construct dedicated bus-only lanes.

Before appearing for voters on the Nov. 5 ballot, the proposal will undergo an independent financial audit and require approval from the state’s comptroller and Nashville’s Metro Council.
