Along Amsterdam road near the I-90 exit, a line of cars waited in traffic Thursday afternoon.
This project is just one of a few in the area along I-90.
Just over a month ago, workers began transforming the North 7th Interchange.
Construction along Bear Canyon starts next week, although officials say they don't expect it to slow traffic along the interstate.
"Looking for speeders, people who maybe want to pass inappropriately," said Trooper Zach Rehbein.
He said Montana Highway Patrol is making sure drivers obey all the orange cones and slower speed limits in the area. They aren't hesitating to pull people over, and tickets are twice the price in construction zones.
But all the road work is creating a new issue- drivers using alternate routes along back roads. Rehbein said they've responded to more area crashes already.
"There have been a few accidents," he said. "Just more of a chance of people getting in a crash."
We checked with drivers to see how it's affecting them.
"I don't find it too much of a problem to tell you the truth," said Bozeman resident David Cook.
Canadian resident Gordon Lipsett, who drove his motorhome through the construction zone, said it wasn't too bad either.
"Yeah we had no problem," he said.
They say they can deal with the traffic, but drivers like Cook said they are using alternate routes steer clear of the construction- and it'll be that way for a while.
"I kind of avoid 90 as much as possible," Cook said. "Since I live here I don't drive 90 that much."
Trooper Rehbein urges drivers to slow down in construction areas and obey all laws- because dealing with the hassle in a safe way is much less of a headache than dealing with a ticket.
