In 2010, Traffic studies completed to determine if traffic capacity was available in two way configuration Veenstra & Kimm of West Des Moines, Iowa identified that this one -way to two -way conversion was feasible. Study determined capacity is present DOT wanted additional traffic study to determine appropriate US 52 routing from Central Ave to US 61/151; IIW completed additional traffic study. Feasibility Study for Dubuque Downtown Intermodal Center selected HMD site • Elm Street Connector needs to be removed to make site work • Traffic Study shows Elm Street, 9th Street, and 11th Street can be converted from one way to two way streets • DOT agrees with two way concept, wants to see implementation plans showing proposed geometric changes and traffic signal changes IIW, P . • ENGINEERS.
