BAY BRIDGE LIFE CYCLE COST ANALYIS COMPLETE

Study available online at mdta.maryland.gov

 

BALTIMORE, MD - The Maryland Transportation Authority (MDTA) completed its Bay Bridge Life Cycle Cost Analysis, a two-year study that established when preservation and maintenance will be required throughout the life cycle of both spans and developed options for adding capacity to the existing crossing and approach roadways based on traffic demand and structural conditions. The study limits include the US 50/301 corridor from Rowe Boulevard in Annapolis to the US 50/301 split on the Eastern Shore.

The study developed a traffic forecast; completed traffic analyses; assessed bridge and roadway maintenance needs; developed multiple conceptual options for adding capacity to the existing crossing and approach roadways; and, developed life cycle costs for each bridge/roadway option based on multiple construction time frames.

The study identified deck and superstructure replacement, painting and cable replacement as just some of the preservation needs anticipated for the future, including a timeline for implementing these improvements.

The life cycle analysis confirmed that the existing Bay Bridge spans are in satisfactory condition, and with programmed and anticipated preservation and maintenance, can be maintained safely through 2065.

The Bay Bridge Life Cycle Cost Analysis is available at http://www.mdta.maryland.gov/Capital_Projects/documents/Bay_Bridge_LCCA_Report_12-2015.pdf.
