MDTA Board Meeting Materials

design is structurally feasible. Between July and November 2025, MDTA awarded five work authorizations totaling approximately $355.3 million for the demolition of the remaining bridge, certain materials (such as, platforms for bridge construction to support cranes and drilling machines), and the installation of these materials. In November 2025, design and preliminary engineering activities were approximately 70 percent complete, and MDTA announced that the total estimated cost to replace the bridge had increased to between $4.3 billion to $5.2 billion and the estimated completion date was extended an additional two years to calendar year 2030. MDTA management advised that the increase and extended timeline was primarily due to increases in the materials cost, a change in the width and height of the new bridge, and the addition of a robust pier protection system to help reduce the likelihood of a similar incident. In addition, the revised estimate included $923.5 million in contingency costs which were not included in the original estimate. In January 2026, MDTA reported to the Maryland General Assembly’s Senate Budget and Taxation Committee and the House Appropriations Committee that it had expended approximately $238 million on the project as of November 2025. This amount included the cost to remove the debris of the bridge collapse, payments for the design-build contractor, and other related costs (such as construction management and inspection services).
