Lyndale Avenue Interchange

Richfield and Bloomington, MN

WSB & Associates, Inc., along with its partners, teamed to provide the City of Richfield with engineering services to complete the design for a new single-point diamond interchange at Lyndale Avenue and I-494.

The cites of Richfield and Bloomington had been pursuing reconstruction of the Lyndale interchange for a decade, or more, to serve the traffic needs in this commercial district along I-494. The close proximity of Lyndale to the I-494 and I-35W interchange posed a challenge along with the need to develop a project that met the access needs of the local businesses. Adequate spacing between entrance and exit ramps on I-494 was needed. The plan also needed to provide for the future upgrade of the I-35W and I-494 interchange. WSB worked with Mn/DOT and the Cities of Richfield and Bloomington to develop a design that accomplished these goals.

This project required the development of a final preliminary layout, final design plans, and construction support. The preliminary phase required WSB to develop an interchange plan for the I-494/I-35W interchange so the Lyndale Avenue Bridge could accommodate the future CD roads emanating from the adjacent interchange. Once the final design was completed, WSB had nine months to complete the final design plans and have it out for bids. This was accomplished through our effective project management techniques and prior work experiences.
