James Canyon Flood Recovery Project Update

Hello -

Work in James Canyon continues to move forward smoothly. The new box culvert at Castle Gulch (photo below) is now in place. Crews will return to this site and at Jenks Gulch at a later date to install the remaining pieces (wing and head walls).

Stream restoration operations are also going well. Crews have successfully diverted James Creek in two stream reaches in order to remove debris and rehabilitate the surrounding floodway (photo below).

KTI is now going to work on the first of several retaining walls and rockeries (native stone retaining walls) just uphill from the James Canyon Drive and Lefthand Canyon Drive intersection. This work will require the installation of a shoofly that will move travelers safely around the work zone. Travel through the shoofly will be controlled by a traffic signal. Timing will be determined by the length of the shoofly. We will do our best to keep wait times at the light as short as possible. This signal will also have optic vehicles sensors. Work at this location is expected to take between 30 and 45 days.

Materials and equipment continue to be delivered to the site on a daily basis. These deliveries and the loading and unloading of trucks will require a single lane closure at various times that will be controlled by flaggers. Please use caution, drive slowly, and give crews room to operate at these locations.

Please let me know if you have any questions or concerns. Thank you for your patience and understanding while we continue work on this project.

Have a good day.
