Marystown Road closed through August Two more roundabouts, trails being constructed

The second phase of construction on Marystown Road/Adams Street from 17th Avenue to Vierling Drive is in progress, with the area expected to reopen to traffic by the end of August. Phase One of the project was completed in 2025 and included con struction of a roundabout at the intersection of Marystown Road and the southbound ramp for Highway 169, which also serves as the access to Tahpah Park. Phase Two includes the construction of a roundabout at the intersec tion of Vierling Drive and Adams Street, which was previously con trolled by a four-way stop, and a roundabout on Marystown Road at the northbound entrance to Highway 169. In addition to roadway and intersection improvements along Marys town Road, lighting, and trees will be installed along both sides of the road. The existing bridge will be retrofitted with trails that are sepa rated from vehicle traffic by raised barriers. During construction, traffic is detoured along 10th Avenue, 17th Ave nue, and Fuller Street. Access to Tahpah Park will be available from both entrances on Vierling Drive and Marystown Road. Detour maps and other project updates are available at www.marys townroad.com . Major construction and traffic impacts are scheduled to begin July 6 at the intersection of Old Carriage Road and Old Carriage Court in the Southbridge area. In recent years, increased vehicle traffic in this bustling development has caused safety and traffic flow issues. The City of Shakopee con ducted a study in 2024 to evaluate options for possible road improve ments and has developed a construction plan based on the study results. The improvements include: ■ Constructing a hybrid roundabout at the intersection of Old Carriage Road and Old Carriage Court (combination of single and multi-lane based on traffic need) ■ Adding a traffic signal at the intersection of Old Carriage Court and the Walmart entrance, providing improved access for the redevelopment area ■ Modifying access points along Old Carriage Court and Old Carriage Road to reduce vehicle conflicts The project will be constructed in multiple phases to maintain access to area businesses. Phase One: July 6–Sept. 25 The first phase will include construction of the roundabout at the Old Carriage Court and Old Carriage Road intersection. This work will begin on July 6 and will be re-opened to traffic no later than Sept. 25. During construction, the intersection will be closed and local traffic will detoured along a temporary road through the Walmart parking

This work will begin after phase one is done, with phase two com plete no later than Oct. 31. During phase two, the new roundabout will be open to traffic, but Old Carriage Court between Southbridge Parkway and the new roundabout will be closed to traffic. Detour signage will be in place for drivers to navigate the closure area. In advance of the July 6 closure date, there will be construction work in the area such as private utility relocation, development construc tion, and staging to prepare the area for construction. To further minimize area impacts, the City included provisions in the project contract to incentivize the contractor to complete construc tion in advance of the required completion dates.
