Annual Transportation Improvement Program(TIP)- Six Year project and funding outlook.


ROAD CLOSURE: N-NE Between 6-NE and 7-NE

Road N-NE between Road 7-NE and Road 6-NE will remain closed through spring of 2025.  Due to Bureau constraints on construction, bridge work is confined to those times when the canals are not running.  Additionally, the bridge will require approximately 3 million in funding outside our current budget.  The reason for the closure is what is known as scour affecting the canal bridge footing. Scour is the removal of material under the footing by fast-moving water. Structural engineers have inspected the bridge; Public Works crews will shore up the area this winter, place temporary piers, and perform demolition of abutment as able. We appreciate everyone’s cooperation while we work to fix this problem. Please follow the Grant County Public Works Department Facebook page for updates.

B-SE NEWS: Grant County Emergency Bailey Bridge Installed, Road B-SE is Now Open to Single Lane Traffic. 

The Grant County Bridge Crew has completed the installation of an Emergency Bailey Bridge over two sets of failing fish passage culverts on Road B-SE southeast of Royal City.  This provides single lane access for a road that has been closed for over (2) years.

Grant County, WA – The two-year closure of Road B-SE has created a life safety issue for families that live on the South side of the closure.  The Emergency Bailey Bridges provide temporary local access, farming access, and life safety passage, while a more permanent solution is being worked on.  The installed Emergency Bailey Bridge is a stout steel panel bridge with a 67-Ton safe capacity and a 5-mph crossing limit.
