Traffic noise analysis

Single-point urban interchanges

A single-point urban interchange (SPUI) can also be called a single-point diamond interchange. The Highway 169 freeway project will use these interchange designs at Main St., School St. and 193rd Ave. This type of highway interchange design was created to help move large volumes of traffic through limited areas of space safely and efficiently. The term "single point" refers to the fact that all through traffic on the arterial street, as well as the traffic turning left onto or off the interchange, can be controlled from a single set of traffic signals.
