Missouri officials have approved a list of more than 800 projects that would be funded if voters approve a sales tax for transportation on the August ballot.
The list endorsed Wednesday by the Missouri Highways and Transportation Commission totals $4.8 billion over a decade for state roads, bridges and other modes of transportation.
Local governments also would get a share of the proposed three-quarters cent sales tax for their own transportation projects.
The state list includes 330 new or improved bridges and 3,255 miles of resurfacing on roads.
The biggest project is the reconstruction and widening of 200 miles of Interstate 70 between the St. Louis and Kansas City areas.
The list also includes improvements for 71 sidewalks, 24 airports, 14 railroads and seven river ports around the state.
