CSAH 112 (formerly TH 12) was once part of Minnesota’s trunk highway system, designed primarily for high-volume traffic flow. After MnDOT completed a bypass in the 2000s, jurisdiction of the old route, now CSAH 112/Wayzata Boulevard, was transferred to Hennepin County. The corridor’s original design did not support local priorities such as pedestrian access, bicycle connections, or community-focused enhancements.
Preliminary Design and Community Engagement
In 2012, Hennepin County selected SRF to lead preliminary design, permitting, and public involvement for the full four-mile corridor. Initial project tasks included:
- Conceptual roadway and trail alignment
- Early-stage stormwater design
- Right-of-way planning and layout development
- Environmental documentation and permitting
- Extensive stakeholder and public engagement
Final Design and Multimodal Improvements
SRF delivered two complete state-aid plan sets for the phased construction of the corridor. Coordination was required with multiple partners, including two municipalities, subconsultants, and corridor business groups.
Key design features included:
- Lakeshore stabilization and a reinforced soil slope (RSS) wall
- Traffic operations planning and staging
- A flexible design approach that added a center turn lane within the existing two-lane section, reducing right-of-way impacts
- Enhanced multimodal safety: trails, sidewalks, upgraded pedestrian ramps, and corridor lighting
SRF supported Hennepin County throughout Phase 1 construction with shop drawing reviews, on-call design support, and construction observation to ensure adherence to project goals.
