Eastbound Bay Bridge deck replacement contract approved, off-peak work to begin in 2023



BALTIMORE, MD—The Maryland Transportation Authority Board on Thursday approved a $140 million construction services contract for the Eastbound Bay Bridge Deck Replacement project, which is expected to begin major construction in fall 2023 with anticipated completion in winter 2025/2026. The MDTA has designed the project, often referred to as a re-decking, to ensure minimal traffic impacts for residents and motorists.

“The MDTA is putting innovation at the forefront to deliver this needed re-decking to enhance safety and preserve the Bay Bridge,” said MDTA Chairman and Maryland Transportation Secretary James F. Ports, Jr. “I want to assure our local communities and Bay Bridge commuters that we’ve designed this project to limit travel impacts in every way we can. When major construction starts in fall 2023, we’ll accomplish major work overnight and have both spans open for drivers during peak periods.”

The project pre-construction process began in July 2021 and allows contractor input during the design phase to best plan and accomplish the work while minimizing impacts for customers, and to ensure a highly qualified contractor is selected. A joint venture team of local firms Corman of Annapolis Junction and McLean Contracting of Glen Burnie performed the pre-construction work. The MDTA Board on Thursday approved the joint venture – now Kokosing McLean – for the construction services contract.

“Unlike the 2019 westbound right lane overlay project, this project will replace the eastbound deck in sections – without the need for 24/7 closures,” said MDTA Executive Director William Pines. “We’ll utilize off-peak lane closures during the day to get work areas ready to ensure successful night shifts. During those overnight shifts we’ll remove portions of the bridge deck, install precast deck panels, secure openings between panels and reopen lanes in time for morning commuters.”

The new pre-cast deck sections will be fabricated off-site and barged to the Bay Bridge. Marine-based equipment will be utilized to replace deck panels and minimize the use of lane closures for most deliveries, resulting in reduced traffic impacts.

When major construction starts in fall 2023, the eastbound span will close at night, weather permitting, with two-way traffic in effect on the westbound span. Crews will remove at least one section of the deck and replace it with a new precast assembled section during the same overnight shift. Temporary closure assemblies will secure the openings between panels, allowing the eastbound span to reopen to traffic each morning. Daytime crews will prepare the next deck section for removal by the overnight crews.

This process is similar to the method used by the MDTA for re-decking the westbound bridge’s suspension span from 2007 to 2010. That project successfully minimized traffic impacts for bridge commuters and local communities.

This eastbound re-decking project will include replacement of the deck floor system, barrier upgrades, major structural rehabilitation of the truss superstructure, lane use signal gantry replacements and utility relocations, as well as off-site stormwater management work.

Some areas of the existing deck of the eastbound Bay Bridge are nearly 50 years old and have reached the end of their service life, based on MDTA’s detailed deck study from 2015. Extensive patching has been performed and continues when eastbound lane closures are available.
