Denver International Airport to Open Diverging Diamond Interchange on Jackson Gap Street at Peña Boulevard

New design intended to enhance safety and reduce delays

DENVER - Oct. 16, 2025 - Those driving to and from shuttle lots and rental car facilities at Denver International Airport (DEN) will soon enjoy a new traffic configuration on Jackson Gap Street at Peña Boulevard. DEN plans to officially open a diverging diamond interchange on the evening of Saturday, October 18. The new configuration will enhance safety, improve operations in the area and allow for future growth.

"Our new diverging diamond interchange on Jackson Gap will improve traffic conditions along a critical section of the Peña Boulevard travel corridor," DEN CEO Phil Washington said. "The new configuration offers a more efficient traffic flow and will greatly reduce delays for area drivers and rental car facility shuttle buses. This is an exciting infrastructure milestone within our Vision 100 strategic plan to serve 100 million annual passengers in the coming years."

The diverging diamond interchange shifts the direction of traffic on Jackson Gap Street. This new design is aimed at ensuring a consistent flow of traffic, increased capacity, and enhanced safety. The design reduces risk to drivers by eliminating left turns across oncoming traffic. Click here to navigate the new interchange.

The diverging diamond interchange is part of Phase 1B and is a portion of the larger Peña Boulevard corridor improvement project focused on sections between E-470 and the Terminal. The full program includes improvements to the entire Peña Boulevard corridor from I-70 to the terminal in upcoming years. The work will be phased into smaller projects and will focus on critical areas first. The section of Peña Bouleveard between I-70 and E-470 is currently undergoing a National Environmental Policy Act (NEPA) study, which will need to be completed prior to starting design or construction. The section of Peña Boulevard between E-470 and Jackson Gap Street is about to begin design to reconstruct the original pavement and to straighten inbound (heading to DEN) Peña Boulevard. This work is intended to replace aging infrastructure and increase safety.

The project to construct the interchange began in April of 2024. Its total cost is nearly $12 million. The work is being completed on schedule and on budget. The opening is weather dependent. Check for alerts at the top of FlyDenver.com for updates on the status of the work.
