Noisewalls
Residents of Minneapolis neighborhoods who live near I-35W experience high noise levels. When I-35W was built decades ago, noise was less of a concern because there was less traffic. Since that time noise levels grew as traffic increased.
As construction improvements along I-35W take place through 2009, Mn/DOT is building noisewalls along north and southbound I-35W between 42nd Street and 35th Street to reduce freeway noise. Crews will begin construction mid-April 2009.
Noisewalls reduce noise by blocking the direct travel of sound waves from a highway to adjacent homes or businesses, forcing them over the top or around the barrier. They are most effective for the first one or two rows of homes at distances up to 500 feet from the barrier. As noise levels decrease with distance, there is a point away from the highway at which noise barriers are no longer effective. They are not designed to eliminate or block all noise.
During construction, Stevens Avenue and 2nd Avenue will be reduced to one lane.
