Work on the River Road Frontage Improvements project in The Dalles will begin Thursday and continue into the month of June. Crestline Construction Company says intermittent one lane road closures and five-to-10 minute delays can be expected throughout the duration of this project. Construction & signage will be segmental as construction progresses along River Road between the former rodeo grounds and the northwestern entrance of Crates Way. Construction will be starting on the southern end of Crates Way near Klindt Drive. Motorists are asked to avoid the area when possible and prepare for short delays during the construction.
