Vehicle access to "A" Mountain is now banned on Mondays after the City of Tucson launched a six-month pilot program this morning.
The city will reopen the park for vehicle access between 11 a.m. and 8 p.m. Tuesday through Sunday.
The goal is to expand access for pedestrians and bicyclists, while maintaining vehicle access on Sentinel Peak, the Tucson Department of Transportation said.
Tucson officials conducted a survey between March and May this year to gather opinions on potential changes.
Of the 2,902 survey respondents, 66% believed the hours needed to be reduced for vehicles, according to Daily Star archives.
Forty-eight percent of respondents also reported regularly using a vehicle to access Sentinel Peak Road.
Before the pilot program, "A" Mountain was open to all visitors from 9 a.m. to 8 p.m. Monday through Saturday and 9 a.m. to 6 p.m. on Sundays.
Tucson City Council voted in September to implement the pilot program.

The rock-and-concrete that adorns Mountain got a patriotic paint job in September 2001 following the 9-11 attacks. Blue and red were added to the letter's traditional white as a show of support for the United States during a time of crisis. University of Arizona student Sarah Burns came up with the idea, the Home Depot pitched in the paint, and more than 60 volunteers provided the labor.
