James Canyon Drive Construction Update – June 26 to 30

Hello -

Expect construction and travel delays to look similar to what is being seen this week in James Canyon. KTI will continue to install cross culverts as they work uphill towards Jamestown. Flaggers will be used to move you safely around the work zones. Delays have been in the 3 to 5 minute range at these spots. Crews will also continue working on stream restoration and vegetation removal operations. There will be short delays when vehicles and equipment are entering and exiting the creek area.

There are now several short sections of roadway that are gravel where cross culverts have been installed (see the photo below for example). Please slow down and use caution when driving or riding over these patches. KTI will be watering these spots to keep dust down while they are unpaved.

The first major concrete box culvert installation is now scheduled to start on Wednesday, July 5. A single-lane shoofly will be built to allow people to travel around the work zone. This will be the first instance where traffic signals will be employed to move travelers in one direction at a time. The signal will be timed to allow the slowest traveler enough time to safely clear the zone, which are typically cyclists. The signals will have optical sensors that can trigger a light change if no one is waiting at the other side or are already in the travel zone. It is extremely important that people do not run the light when it is red. Not only could this result in a head-on crash, but it will also reset the signal's timing and force people coming from the other direction to wait through another cycle before receiving a green light.

No work will take place on Monday, July 3 or Tuesday, July 4 in observation of Independence Day. Happy Birthday, America!
