SPEARFISH, SD - The traffic pattern has been re-routed on East Colorado Boulevard at the intersection of Maitland Road through October 31 for the 16-inch sewer force main pipe sleeve passing under East Colorado Boulevard. Speed will be reduced to 10 mph in this area, and both east and westbound traffic will be diverted onto a temporary gravel road surface around the work area. The three-way stop intersection will be shifted approximately 100 feet to the south. Please obey the traffic control devices and reduced speed in this area. Regular traffic pattern should be restored the afternoon of October 31st.
Starting November 7th, speed limits will be reduced to 25 mph near work areas on East Colorado Boulevard from False Bottom Creek Bridge to Highway 85. Shoulder work includes the installation of 21-inch sewer gravity main and 16-inch force main upsize. Concrete barriers will be installed along the shoulder to protect the traveling public and construction operations. Temporary stops with flaggers will be utilized for equipment entering and exiting the job site.
Completion date for the project is September 1, 2023.
