RTD spokesperson Scott Reed said the driver entered the northbound High Occupancy Vehicle lanes of Interstate 25 and traveled south. Colorado State Patrol and Denver Police closed the HOV lanes for about an hour while they worked to turn the long bus around, KUSA-TV, Denver, reported Wednesday,
"This shouldn't have happened," RTD spokesperson Scott Reed said. "We were very fortunate."
Reed said the driver may have found signs at the interstate entrance misleading.
"We know based upon our initial investigation that we need to do something to modify the signage there," Reed said.
Police ticketed the driver for careless driving, The Denver Post reported.
A similar incident in 2010 on approximately the same stretch of highway led to the resignation of an RTD driver, the Post said.
