M-39 Reconstruction Project Overview
Value Engineering, serving as a sub-consultant, will provide complex roadway design services for the M-39 freeway and associated ramps within Detroit and Dearborn, specifically from Cathedral St to Tireman Rd. M-39 (Southfield Freeway), originally constructed in the 1960s, spans through Detroit and Dearborn. This includes developing a comprehensive 3-D model for alignments, profiles, unique templates, and tie-ins at ramp terminal intersections, among other detailed design aspects.
This project entails a comprehensive 4R reconstruction of the M-39 freeway and all ramps within the specified limits, excluding the I-96 interchange. Key components of the project include:

This project entails a comprehensive 4R reconstruction of the M-39 freeway and all ramps within the specified limits, excluding the I-96 interchange. Key components of the project include:
- Complete removal and replacement of mainline and ramp pavements.
- Installation of single-face concrete median barriers.
- Modification or replacement of service road screening walls.
- Upgrading storm sewer systems with oversized dual trunk lines.
- Analysis and upgrade of pump stations.
- Replacement of raised outside shoulders with flush shoulders.
- Installation of freeway lighting, signing, permanent pavement marking, landscaping, and other associated works.
- Signal work at ramp terminal intersections is not within the scope.
