People planning to attend commencement at the University of ÃÛÌÇÖ±²¥ at Boulder on Friday morning, May 12, are encouraged to leave ample time for driving, particularly people arriving via U.S. 36. Traffic volume is expected to be about half of game-day traffic during ÃÛÌÇÖ±²¥Â’s football season, which sometimes clogs the Turnpike even without construction delays. Because of construction work along U.S. 36, similar tie-ups could result, although all lanes reportedly will be open.
