A huge topic in the Treasure Valley is how much it has grown in recent years. If you use major roads to get to and from work, you probably feel that growth in the amount of traffic.

One intersection that local agencies are eyeing to make changes to is the State and Glenwood streets intersection in Boise.

The Ada County Highway District and the Idaho Transportation Department are conducting a 12-month study that has included property and business owners and local agencies.

In the study, officials say every day 60,000 vehicles, 90 bicyclists and 135 pedestrians come through this corridor. They expect all of those numbers to grow as time goes on.

"I think anybody who has driven through there now knows that it's already one of the most congested intersections in the city," said ACHD Senior Transportation Planner David Corcoran. "That intersection is just going to continue to get more and more congestion through 2040."

That means cars will need more room to move through smoothly.

"We need to get on the ball, especially as more development occurs in that area and then west of the city," Corcoran said.

Back in August, ACHD and ITD held a public meeting where several different expansion suggestions for that intersection were discussed.

"Based on traffic projections coming through the area what we can tell is that it's going to be difficult to widen out the intersection more and have traffic continue to flow, so we have to look at more creative design options," said Corcoran.

One option is what's called a "no build" where they don't make any changes at all.

The second option would be a median U-turn that potentially looks similar to State Street and Veterans Memorial Parkway.

"Another would be a quadrant type intersection and another would be a partial displaced left turn intersection," Corcoran said.

He says they're getting creative to make sure whatever changes occur improve functionally for those with disabilities, make it easier for pedestrians and bicyclists to navigate and meet ACHD and ITD standards.

"These are ideas that have been implemented successfully in other cities of similar size throughout the country," said Corcoran.

In February there will be another public meeting with more specific concepts. Shortly after that ACHD says they hope to have a preferred design.

They hope to finish the concept study sometime in the spring or summer. As far as construction goes, Corcoran says they aren't sure how quickly that will happen.
