This railroad crossing is unique in that it has four separate at-grade rail crossings at a skewed angle to the roadway.

Federal and State Aid funds have been allocated for the design and construction of the following elements to improve safety and level of service:

  • Upgraded signal equipment and crossing gates
  • Raised roadway medians to prevent illegal vehicle maneuvers
