MDTA added additional funding authority to the Phase 1 contract to conduct static and lateral load testing for the bridge foundation which will use 96-inch diameter steel pipe piles for the main cable-stayed span foundations. Performing the pile load test to determine the axial and lateral load capacities for these piles allows MDTA to determine the optimum pile lengths and will add certainty to development of the overall cost for the Project. The additional cost for this work is $42,956,739.84. MDTA determined extending the Phase 1 design stage to 70% will allow detailed design and minimize contingency for risk in the BPP. MDTA has added additional funding of $55,000,000 for this added work. With the additional scope of work, the total Phase 1 contract value was increased from $73,000,000 to $160,956,739.84. At this time, MDTA has extended the Phase 1 contract duration to June 30, 2026. Phase 2 MDTA and the Design-Builder are currently working to identify Phase 2 Early Work Packages (EWP) to advance the project work and schedule. These EWPs include demolition of remaining portions of the work, procurement and installation of piles for the cable-stay span foundations, procurement and installation of temporary access trestle, foundation footing procurement and installation, environmental mitigation, leasing properties to support the construction work, materials testing, environmental mitigation, and formwork for the cable-stay span foundations and towers.
On June 4, 2025, MDTA and the Design-Builder executed the First Amendment to the Contract with a not-to-exceed amount of $250,000,000 to perform work under the Early Work Packages.
MDTA continues to work through the cost estimation process for a design that incorporates current federal standards for marine shipping and roadways, as well as specific needs of the state.
Recent pre-construction activity and updated datapoints are being utilized to provide a better understanding of the cost and schedule estimates for the project at 50-70% design. MDTA remains committed to delivering the Key Bridge Rebuild with safety, economic vitality, and sound stewardship of taxpayer dollars being top of mind.
