I-90 Interchange 17 in Newton Corner is a rotary-style interchange over the Massachusetts Turnpike´s Boston Extension. Eleven roadway elements (exclusive of various curb cuts) load or unload vehicles onto or away from the rotary, serving both local and regional traffic. Furthermore, the Newton Corner interchange is unusual in its ramp system´s being fully and directly integrated into the local roadway system and the dense, urban, commercial, and residential environment. Regional and local traffic is fully mixed in a small amount of space.

A study conducted by the URS Corporation in 2002 recommended some short-term improvements for the interchange. This study refined the URS recommendations, made additional short-term recommendations, and developed some long-term design concepts.
