Glacier High School administrators remind the community that all but one entrance road to the school will be closed starting Monday as a safety precaution during a heavy-hauling phase of construction on the U.S. 93 bypass.

The closure is expected to be in effect through March 12 for 24 hours a day.

Transport trucks will haul 500 loads of pit-run gravel — about 50 tons per truckload — daily between LHC on Stillwater Road and the bypass construction site south of Glacier High School.

The trucks will load at LHC, travel south on Stillwater Road and then east in a single lane on West Reserve and Old Reserve Drive and then turn in to the construction site.

High school administrators worked with the Montana Department of Transportation to create a modified traffic plan to and from the school.

The only public entrance to the school will be from Stillwater Road on the west side. That intersection at Stillwater Road near Flathead National Forest offices will be controlled by a traffic signal.

Both the north and east entrance roads to Glacier will be closed to public traffic; the north entrance to will be restricted to school buses only.

The closure of the eastern end of Wolfpack Way where it meets Old Reserve Drive likely will have the greatest impact on Glacier students and visitors.

Reserve will only have one lane open to eastbound traffic.

The modified traffic plan is to prevent vehicles from merging or crossing in front of trucks.

School administrators hope that people will consider transportation alternatives such as car pooling, taking the bus or leaving early to minimize a rush of traffic.
