The Colorado Department of Transportation (CDOT) is designing a plan to make numerous safety and traffic upgrades at the Exit 150 interchange on Interstate 25, approximately five miles north of Pueblo. The main issue is that traffic in both directions under I-25 must share a single-lane tunnel, which can make it difficult for drivers exiting the freeway to see approaching traffic. CDOT's solution is to replace the tunnel with a three-span bridge and add a roundabout, with construction set to begin next year and take 18 months to complete at a cost of $40-45 million.
Why it matters
The Exit 150 interchange serves as an important access point to Pueblo West and sees heavy eastbound traffic from Pueblo West heading north to Colorado Springs. The current single-lane tunnel setup has led to safety concerns and traffic congestion, prompting CDOT to undertake this major infrastructure project to improve traffic flow and driver safety.
The details
CDOT's plan includes replacing the existing single-lane tunnel under I-25 with a new three-span bridge, similar to the bridge at the Dillon Drive interchange farther south. The project will also add a roundabout on the west side of the bridge. Most of the construction will take place on the west side of the bridge, and the entire project is expected to take 18 months to complete.
- The project is set to begin construction next year.
