There’s new information on the latest plans for the Northgate expansion project in Pocatello and Chubbuck.

The Idaho Transportation Department showed off the new plans at a public meeting in Chubbuck City Hall Thursday night.

Right now drivers only have a lonely stretch of highway as they travel just north of Pocatello and Chubbuck.

With plans to add an interchange here, many ideas are circulating what that may look like.

Now ITD has a new idea.

“So the original one had, we call a ‘dog bone’ interchange, so it had the round-abouts on both sides and we’ve gone away from that after completing internal studies to what you see on here, the standard diamond,” says Greydon Wright, ITD Project Manager for Northgate Interchange.

One of the displays ITD presented to the public, shows where the Northgate Bridge will be crossing over Interstate 15.

“So on this one, we’re trying to be very transparent with the public and show them, hey this is what’s going to happen, but instead of being a big surprise, it’s part of our outreach,” says Wright.

Last week the transportation board gave the green light to move forward and complete the design of the project.

After the design phase is complete, they hope to begin the bidding process and start construction in the Spring.

“It’s actually been a fantastic experience.  They’re all on the same page.  They’re all trying to accomplish the same goal and so all the parties have worked very well together and the developers also involved with this have been just great to work with and it’s gone really smooth,” says Wright.

Local cities and counties will be responsible for any new local roads connecting to the new interchange.

That will need to happen before the interchange is complete.

People using the road make mistakes (like running stop signs and red lights), always have and always will. Crashes will always be with us, but they need not result in fatalities or serious injury. Modern roundabouts are the safest form of intersection in the world - the intersection type with the lowest risk of fatal or serious injury crashes - (much more so than comparable signals). Modern roundabouts require a change in speed and alter the geometry of one of the most dangerous parts of the system - intersections. The reduction in speed and sideswipe geometry mean that, more often than not, when a crash does happen at a modern roundabout, you usually need a tow truck, not an ambulance. Roundabouts are one of nine proven road safety features (FHWA).
The life saved may be your own.
