Hello -

Activity in Fourmile Canyon continues at a fast pace and will only intensify over the coming months. If you've traveled west of Salina Junction or up through Gold Run, you've seen trucks, heavy machinery, and numerous workers up and down both corridors.

This means that the already limited amount of available space, both on and off the road, is getting even scarcer. Loads of material and trucks carrying heavy equipment are being moved in and out of the canyon each day. This mean lots and lots of big trucks moving up and down between Boulder Canyon and the work sites.

With the added roadway activity, it is of the utmost importance that everyone keeps their eyes on the road and stays acutely aware of their surroundings. When large semi trucks are brought up or down the road, crews have been using pilot cars like the one below to alert oncoming travelers that an oversized vehicle is coming in order provide warning so that people can give them room around the many tight corners.

Oversize Load Pilot Truck

Our crews have been informed that speeding will not be tolerated, and to avoid using engine brakes unless they are equipped with engine mufflers. We're also asking residents and visitors to please drive the speed limit. If you witness a truck from either construction site speeding or using their engine (Jake) brake, please contact me so I can address the issue immediately. Look out for pilot trucks and please pay attention to flaggers. Both methods are used to keep everyone as safe as possible.

Thank you for your patience and understanding.

Have a good day.
