🚨 MAS2U LLC Proudly Supported the Howard Street Tunnel Modernization Project in Baltimore
Baltimore, MD – May 2026 – MAS2U LLC, a certified Minority Business Enterprise (MBE), Disadvantaged Business Enterprise (DBE), and Women’s Business Enterprise (WBE), is proud to announce its key supporting role in the successful Howard Street Tunnel Modernization Project alongside CSX Transportation and the Skanska-Fay Joint Venture.
This major infrastructure upgrade modernized the historic 1895 Howard Street Tunnel, raising its vertical clearance from approximately 19 feet to 21 feet. The improvement now allows double-stacked intermodal container trains to pass through, significantly increasing freight capacity along the vital I-95 rail corridor between Baltimore and the Northeast/Midwest.
MAS2U’s 24/7 On-Site Contribution
Throughout the intense construction phase, MAS2U LLC provided round-the-clock equipment maintenance and repair services — working 24 hours a day, 7 days a week directly on site.
Our ASE-certified mobile mechanics kept the heavy equipment and vehicles performing the actual tunnel work in peak operating condition, including excavators, loaders, specialized tunnel machinery, and support fleet vehicles. By delivering fast, on-location repairs and preventive maintenance, MAS2U helped minimize costly downtime in a true 24/7 operation.
This critical support contributed to the project being substantially completed in September 2025 — nearly two years ahead of the original August 2027 schedule.
A Milestone for Certified Local Businesses
“Being trusted to maintain the equipment on such a high-profile infrastructure project is a tremendous honor for our family-owned company,” said Anatiara Curtis (Ana), Owner of MAS2U LLC.
“We brought the same dedication, speed, and reliability that define our mobile service to help deliver this game-changing upgrade for the Port of Baltimore and the entire region.”
