• Jul 21, 2022: DC Department of Transportation (DDOT) I-295 over South Capitol Street Bridge Rehabilitation (Bridge 1016 NB & 1017 SB)
    on July 21, 2022 at 5:00 pm

    The District Department of Transportation (DDOT) needed an innovative solution to upgrade the deteriorated Anacostia Freeway (I-295) bridges over South Capitol Street in Washington, DC. With high traffic counts on this key commuter route, minimizing the construction schedule was a primary objective. DDOT tasked Johnson, Mirmiran & Thompson, Inc. (JMT) with developing the solution. Because the bridge substructures remained usable, JMT proposed replacing the superstructure with precast modular deck units comprised of steel plate girders, tied together with a UHPC closure pour. The new bridge superstructures were designed to fit within the geometric constraints of the heavily skewed existing substructures. The steel girders topped with concrete deck were fabricated in a controlled environment before each modular unit was shipped to the construction site. Installation and construction were completed in 2018 in several phases on each bridge using temporary weekend detours. By applying ABC principles and meticulously planning the proposed weekend construction sequences, the project was completed within six months, minimally impacting regular motorists on their daily commutes. This presentation includes design and construction details and lessons learned. View on site | Email this event

  • Dec 7, 2022: 2022 International Accelerated Bridge Construction Conference: Including Advanced Bridge Technologies at Hyatt Regency Miami
    on December 7, 2022 at 5:00 am

    The 2022 International Accelerated Bridge Construction Conference: Including Advanced Bridge Technologies will be a premier bridge engineering conference that is co-sponsored by 32 State DOTs, the Federal Highway Administration, and other bridge-related organizations. In 2022, the conference will also include topics related to advance technologies that affect all bridges, in addition to influencing the projects that uses Accelerated Bridge Construction (ABC). This Conference will also include keynote talks and technical presentations on Advanced Technologies that are transforming bridge engineering in general and ABC specifically. These technologies include automation and additive manufacturing (3D Printing) using concrete and steel, and advancements in UHPC. The 2022 conference will be held face-to-face on December 7-9, 2022 at the Hyatt Regency Miami located in Miami, Florida. Several ABC workshops will be held on Wednesday, December 7, one day prior to the conference. Details of the workshops can be found by clicking here. 2022 Call for Abstracts: The deadline to submit abstracts was April 22, 2022. Those interested in submitting an abstract to the next conference can stay tuned for further details. View on site | Email this event
