Federal Railroad Administration requires a complete and current grade crossing inventory for each state. States and railroads update this grade crossing inventory information which is collected and maintained by the U.S. DOT and is then used by states in making safety improvement decisions.
Stevens was asked to evaluate 350 railroad crossings across the northern part of Minnesota for MnDOT’s crossing inventory.
This project includes inspecting the crossings for safe stopping sight distance, advanced warning signs, and sight obstructions. It also includes inspecting the crossing surface, traffic control devices, and channelization devices. Along with each inspection, there are 12 photos that need to be taken per crossing.
