IBC 24-42: Bridge Rehabilitation in the Heart of Our Nation’s Capital
Ahmad Faqiri and Jeffrey Hollands, P.E., HDR, Vienna, VA

Over half a mile of an elevated portion of the I-695 Freeway in Washington, DC is comprised of three main bridges and 10 ramp bridges. Bridge 1103 and its ramps, approximately 800 feet long, are a series of simple prestressed bulb-tee spans ranging from 50 to 150 feet long supported on reinforced concrete pier bents. Bridges 1104 and 1109, approximately 550 feet and 1500 feet long respectively, are primarily a series of simple steel plate girder spans ranging from 50 feet to 260 feet long supported on steel cross-girders and reinforced concrete columns. Several of the steel plate girder spans include pin and hanger connections. Theses bridges span over parking lots, local roads, and CSX facilities, resulting in complex bridge shapes. Built in the 1960s and rehabilitated in 1990s, these bridges are in poor condition, needing deck repair, joint replacement, beam repair, pin and hanger retrofit, bearing repair, pier/cross girder repair, and column/abutment repair. Due to the highly urbanized location of this project and the importance of the freeway to the transportation network of the US capital city, MOT is a major component of the project. To mitigate the risk and reduce the construction duration, the design team has proposed accelerated bridge construction methods such as use of ultra-high-performance concrete for the bridge deck overlay and some of the other repairs such as link slabs and joint replacements. Additional innovative rehabilitation techniques, to enhance bridge preservation, include metalizing of concrete and catcher beams at pin-and-hanger locations.

IBC 24-43: Pittsburgh International Airport Terminal Modernization – Construction overview and opening preview
Kevin O’Connor, HDR, Pittsburgh, PA

The Pittsburgh International Airport Terminal Modernization Program (PIT-TMP) will be approximately 90% complete at the time of the IBC in 2024. When the 2025 IBC comes back to Pittsburgh the Airport will be completed and open, and many of the conference attendees will pass through the new facility. The PIT-TMP is a terminal and roadway project that includes architectural and art elements as part of the Terminal Front Bridge and retaining walls. This presentation will show construction photos of the nearly complete facility and compare to renderings and mockups that were produced in design to illustrate the successful execution of the project vision. The PIT-TMP was designed using an overarching concept of Nature, Technology, and Community (NaTeCo). This concept is evident in the design of the Terminal, the bridge and retaining walls, and the terminal curbs on the bridge. The bridge design team also paid special attention to the user experience at the terminal curbs on the bridge, which is an area that is often neglected in airport design.
