The $55 million I-95 Deck Rehabilitation and Joint Replacement project, located in the heart of Baltimore between I-695 and the Ft. McHenry Tunnel, consisted of the rehabilitation of 241,643 SY of existing bridge decks along Interstate 95 through Baltimore City. This was the largest Latex Modified Concrete (LMC) rehabilitation project awarded as a single contract in the United States, and the largest LMC project ever undertaken by Wagman.

Deck rehabilitations using hydro-demolition followed by LMC overlay and expansion joint modifications were performed on 28 bridges. The work was performed to blend into the original construction seamlessly while improving ride quality and performance of the bridge decks.

Key Challenges & Project Details

  • Wagman utilized 236 miles of temporary pavement markings, 20 miles of permanent pavement markings, and 52 miles of temporary concrete barriers to alert and direct the traveling public.
  • Crews used an average of 27,000 gallons of water daily, and approximately 12 million gallons of water over the entire project.
  • In an effort to be environmentally friendly, reduce water usage, and perform within environmental requirements, Wagman developed a plan to capture all of the hydro-demolition run-off water and then treat, clean, and test the water for compliance with regulatory discharge requirements. The water was eventually discharged through the local storm sewers.
  • The project included an aggressive public outreach campaign.
  • Throughout construction, 42 individual traffic shifts were performed, with all through lanes on I-95 maintained during peak travel hours.
  • Per Maryland Transportation Authority’s specifications, grooving services were included in the project scope of work for a safer finished roadway.
  • The project was safely delivered within an extremely compressed schedule.

Project Fun Facts

  • I-95 is one of the most heavily traveled highways located in the downtown metropolitan Baltimore area.

  • Construction activities were coordinated around two presidential visits, and Sailabration, which celebrated the 200th year of the Star Spangled Banner.

  • Hydro demolition work uses water pressures up to 40,000 psi.
