What’s the Latest on the Northbound Interstate 270 Ramp to Westbound Route 364?

To reduce the impact to commuters during the construction of the western portion of Interstate 64, the construction on the ramp will begin in summer 2010.

What Is The Problem With The Existing Northbound Interstate 270 Ramp To Westbound Route 364?

The existing loop ramp from northbound Interstate 270 to westbound Route 364 is not designed to handle current traffic volumes, which results in daily congestion. In fall 2003, approximately 3,200 vehicles were using this ramp. In fall 2004, more than 11,000 vehicles were using this ramp. There are also conflicts between vehicles merging onto westbound Route 364 and vehicles merging onto the ramp to southbound Interstate 270. This creates a "weaving movement" and contributes to congestion.

What Is The Proposed Solution?

MoDOT will construct a new two-lane circular ramp from northbound Interstate 270 to westbound Route 364.
