Thaynes Canyon Drive will become a one-way westbound street, and the 3 Blue will reroute onto Three Kings Drive to Payday Drive before crossing state Route 224 to Holiday Ranch Loop Road.
During construction the Webster Drive and Hotel Park City bus stops will be temporarily closed.
Other buses will service the post office, Saddle View and Peaks Hotel stops.
The detour is expected through June.
Bus routes, transit schedules and a real-time bus tracker are available here.
