Two major alternatives are being explored. The first option would be a two lane rotary. This would have the greatest impact on the wetlands. The second option would be a signalized intersection. The signalized intersection would have less impact on the wetlands than the first option. In both scenarios, the Hartwell Ave Bridge will be replaced. Mr. Hill stated that the rotary option will have over 5,000 sq. ft. of wetlands disturbance, but they , explained that they could use a Limited Project Provisionbecause the site could be considered a risk to public safety.
