Recommended Improvements Updated for US 35 Interchange

Comments on the updated recommendation accepted through April 19

The recommended design for the I-70 and US 35 interchange is being updated as part of the Revive I-70 project. More robust improvements are now planned at the interchange. The modifications include a tight diamond interchange and two single-lane roundabouts. The updates will allow the existing loop ramps to be removed and eliminate weaving movements from entrance and exit ramps.

Initial recommendations at the interchange included only partial modifications to improve the acceleration and deceleration length of each ramp movement. The updated design is expected to better improve traffic flow and safety.

Roundabouts have been proven to greatly improve safety while also improving traffic flow. They reduce conflict points and serious injury crashes. They’re designed in accordance with modern design standards that accommodate commercial trucks and emergency vehicles and the need for wide turning space.

Impacts are also reduced with the design modification.
