Chip Sealing Schedule
Glacier National Park is chip sealing most of its asphalt paved roadways this year (two sections of the Going-to-the-Sun Road are also under major construction and will not be chip sealed). The purpose of chip sealing and other pavement preservation techniques is to protect the significant investment we have in our roads throughout the park. The cost to replace roads is extremely high so it makes sense to preserve them and extend their life as long as we can. This is exactly what chip sealing does, it puts a protective coating of bituminous material and rock chips directly on the asphalt to extend the life of the road surface by 5 to 7 years. Glacier's roads have not been chip sealed in over ten years and so we were on the verge of losing many sections of them.
Please excuse the construction this season. You should only be inconvenienced 15 minutes in either direction if you encounter the chip sealing operations.
