St. Anthony 2040 Comprehensive Plan Chapter 6: Transportation 83 Recommendations from Recent Traffic Study Due to the proposed Southern Gateway redevelopment, a traffic study was recently completed. The 15-acre redevelopment site is located in the northeast quadrant of the intersection of Kenzie Terrace (CR 153) and NE Stinson Parkway. The proposed Southern Gateway development is anticipated to consist of a combination of multi-family, senior living, and assisted living residential units, totaling 414 units. As a result of the traffic study completed for this project, specific operational improvements were outlined to support the safe and efficient performance of the transportation system in and around the redevelopment site. Recommendations were generally categorized into one group occurring with site development (2019), while others are intended to be implemented over a longer timeframe as the area continues to develop (2030). Traffic study improvements recommended for implementation at the same time as the redevelopment include: • Optimize signal time and coordination between St. Anthony Boulevard intersections at New Brighton Boulevard (CSAH 88) and Silver Lake Road/Kenzie Terrace (CR 153) • Lengthen southwest bound left-turn lane from Silver Lake Road to southeast St. Anthony Boulevard from 100 feet to 175 feet • Lengthen northwest bound left-turn lane from St. Anthony Boulevard to southbound New Brighton Boulevard (CSAH 88) from 125 feet to 225 feet • Lengthen westbound left-turn lane from Kenzie Terrace to southbound Stinson Parkway when the Bremer Bank Building site is redeveloped • Lengthen the northbound left-turn lane from Stinson Parkway to westbound Lowry Avenue from 150 feet to 250 feet • At the proposed site driveway on Kenzie Terrace (CR 153) provide: o Two lanes exiting the site (one left-turn and one through/right-turn lane) o Left-turn lane from Kenzie Terrace (CR 153) into the site o Right-turn lane from Kenzie Terrace (CR 153) into the site Traffic study improvements recommended for long-term implementation include: • Consider a dual roundabout or other traffic control improvements at the St. Anthony Boulevard intersections at New Brighton Boulevard (CSAH 88) and Silver Lake Road (CR 136)/Kenzie Terrace (CR 153) • Consider a roundabout or other intersection control improvements at the intersection of Kenzie Terrace (CR 153)/Lowry Avenue and Stinson Parkway These recommended improvements are included in the list of Transportation Implementation Strategies outlined in FIGURE 6-18 and FIGURE 6-19, Roadway Strategies.
