Ongoing projects

Robinson Road realignment

Project: The project will align Robinson Road across Hanna Road. The project will include realigning a portion of the Union Pacific Railroad, which is crossed by Robinson Road.


Update: Oak Ridge North City Council have said it will take one to three months to deconstruct and rebuild the railroad crossing across Robinson Road. Public Works Director James Corn told council members that no timeframe for the relocation of the Union Pacific Railroad crossing of Robinson Road has been established, which could push completion of the project to March. A new railroad crossing will be built as part of the realignment effort, but the existing crossing will still be passable until the new crossing is complete, he said. The project has also faced several delays as a result of utility line conflicts.
  • Timeline: February-TBD
  • Cost: $7.42 million
  • Funding source: city of Oak Ridge North
