The Missouri Department of Transportation is delaying the startup of its program to repair 800 of the state’s worst bridges. The contract for the work had been expected this month but State Transportation Director Pete Rahn says resolution of legal issues will delay the start until September or October. Two companies have bid on the project but the size of the bonds required is causing concerns that one of the bidders might pull out. State law requires at least two bidders. The legislature failed to pass a bill clarifying the bonding requirement this spring.
