I-69 Corridor Reconstruction: Miles of Freeway, Seventeen Bridges, One Unified Effort
This extensive infrastructure improvement project focuses on reconstructing the I-69 freeway from west of the Fenton Road bridge to Dort Highway (M-54), including ramp rehabilitation at the I-69/I-475 interchange. The project features high friction surface treatment along I-475 and ramp taper modifications to meet current MDOT design standards. A dedicated drainage study drove the enhancement of the I-69 median drainage system, transitioning from a metal edge configuration to a median barrier wall design that delivers improved performance and greater capacity. It’s the kind of forward-thinking solution that protects infrastructure and surrounding communities for decades.
Bridge rehabilitation stands at the heart of this effort, encompassing seventeen structures across the corridor. That includes seven full deck replacements, two superstructure replacements, and five structures receiving targeted preventive maintenance. The scope also integrates epoxy overlays, deck patching, and focused repairs engineered for long-term safety and structural longevity. Pedestrian fencing and mesh panel replacements were woven in alongside Constraint Induced Fatigue remediation for six bridges, because every detail matters when people’s daily commutes are at stake.
Smarter Systems, Safer Travel, Stronger Connections
Beyond structural upgrades, the project delivers comprehensive lighting improvements, freeway and local road signing enhancements, guardrail replacements, and geometric adjustments, each calibrated to boost safety and traffic flow across the network.
Our team implemented innovative maintenance of traffic strategies that kept the community moving during construction, backed by a comprehensive Transportation Management Plan (TMP) designed to minimize disruption. On the environmental side, we coordinated soil erosion control measures, managed utility coordination across multiple stakeholders, and navigated the full permit application process to keep the project on track. Together, these coordinated improvements will significantly enhance safety, durability, and mobility along this crucial corridor, delivering infrastructure the traveling public can count
