A proposal to allow bars and restaurants to serve alcohol past the state's current 2 a.m. deadline moved forward to the Colorado House floor Wednesday.

When introduced earlier this month, the bill allowed cities the opportunity to keep bars open until 7 a.m., but on Wednesday it was amended to a 4:30 a.m. cutoff.

The 4:30 a.m. amendment came because public transit schedules begin closer to that time and there were also concerns from local government officials.
