The automobile was not very old before it became apparent that a "Trans Mountain Road" was desired through Glacier National Park.

After a decade of engineering, bids were contracted in June, 1925 and work began on the more difficult west side almost immediately.

Incredibly, the road through the cliffs to Logan Pass was opened to the public in June of 1929. This remained a popular Glacier Park side trip while work on the east side progressed.

With the completion of the east side tunnel during the autumn of 1932, the road finally crossed the Continental Divide.

Greatly impacted by the automobile, the Great Northern Railway promoted this new route as the "Logan Pass Detour" in an effort to increase passenger traffic on it's rail service to Glacier National Park.

On July 15, 1933 more than 4,000 people attended the dedication ceremony held on the Continental Divide at Logan Pass.

The name of the road was changed in honor of nearby Going-to-the-Sun Mountain of Blackfeet lore, telling the story of "the one who helped us and returned to his home in the sun" by climbing this mountain.

The Going-to-the-Sun Road follows the original route exactly as it was surveyed and blasted out so many years ago.

Today's drivers will however, find a well maintained, all weather asphalt surface with ample pullouts to enjoy the view.

Although this road is only about 50 miles in length, at least a half day should be spent in order to fully appreciate this engineering marvel and to view the alpine scenery.

The speed limits are set low and in the alpine portions of the west side, winding curves limit speed.

Because of the spectacular scenery, pullouts have been constructed so that slower vehicles may let others pass. These are generally situated in a vista well suited for photography.

Use care if wildlife is observed near the road, other drivers are looking at it, not other traffic.

Vehicle length and width restrictions apply on the alpine areas of Going-to-the-Sun Road. The entrance stations will be able to determine if your vehicle is oversize. Signs are posted for those that know their vehicle's length.

The free shuttle service runs over the road from the transit center near Apgar to the St. Mary visitor center.

Bicycles have restricted areas during peak hours due to traffic concerns. Signs are posted to advise.

Logan Pass Visitor's Center opens soon after the road is cleared of snow. Restrooms, educational exhibits and book sales are offered here. Rangers are often available to answer questions or point out wildlife with binoculars.

During the peak season, mid-day parking at Logan Pass can be a problem, half hour delays can occur if the lot is full. Go early and increase the possibility of seeing morning wildlife.

Reconstruction proceeds during the summer months. Delays are of short duration and occasionally, automated traffic lights are used to control one way traffic.

Cell phone and mobile reception is poor on the upper west side of the road and is spotty to about mid way on St. Mary Lake on the east side.

Many cyclists reach Logan Pass by bicycle each summer. Hours are restricted during certain hours due to traffic concerns. Signs are posted along the road advising of limited hours for cyclists.

Spring visitors are allowed to bicycle on gated portions of the Going-to-the-Sun road as it drys out after plowing.

Snowbanks along the road can be many feet deep.

When the conditions are prime, avalanches may be safely observed, leaping the cliffs above.
