US 6 Elk Creek Bridge Replacement in New Castle | Construction Phase

About the Project

The project consists of replacing the US 6 Elk Creek Bridge structure over Elk Creek on the west end of town at Mile Point 105.8. A detour is being constructed that will use the existing truss bridge relocated to the south of the existing location so traffic will remain in a two lane configuration while the new bridge structure is being built.

Work on this project includes:

  • Relocating utilities
  • Building retaining walls
  • Shoring up the banks of Elk Creek with riprap
  • Installing new guardrails
  • Implementing erosion control measures
  • Applying final pavement striping
