ST. JOSEPH, Mo. – Evening signal work will affect motorists traveling on U.S. Hwy 169 (Belt Highway) and Route YY (Mitchell Avenue) through St. Joseph next week.

Crews working with the Missouri Department of Transportation will begin at approximately 6 p.m. Monday evening, Sept. 12, to upgrade the left-turn signals at the intersection to flashing yellow arrows, along with other routine maintenance. The work will require crews to close the turn lanes in order to change out the signals heads, signs and vehicle detection system.

During different portions of the project, the signals will be inoperable and stop signs will be in place. Drivers are reminded that whenever a signal is dark or in flash mode, the intersection should be treated as a four-way stop.

Crews hope to have the work completed by 7 a.m. Even after the signals are operational, workers will be present at the intersection performing maintenance work. Motorists should use extra caution and may encounter delays throughout the night.
