Details of Interstate 395 work provided
Maryland Transportation Authority spokeswoman Teri Moss provided some additional details about plans for preservation work on Interstate 395, the spur leading of Interstate 95 into downtown Baltimore. She wrote:
The 395 project to repair section loss and spot-paint beam ends, as of now, is scheduled to advertise March 1, 2011 with notice to proceed September, 2011. This project will have minor maintenance of traffic (MOT) requirements.
I received further clarification. Another separate project to perform deck-sealing and joint repairs is scheduled for construction in (calendar year) 2013. Additionally, joint repair work will be performed on various bridges on I-95 south of the tunnel, possibly beginning this fall or winter.
In reference to the condition, the substructure ratings for all of the bridges south of the tunnel, including the I-395 interchange range from 6 (satisfactory) to 7 (good), with the exception of Gwynn’s Falls which is a 5 (fair) based on a scale of 0-9. Inspections were completed in this area this spring.
Moss went on to explain that "section loss and spot-paint beam ends" means bolting new steel plates to restore sections of the girders that are rusted due to normal environmental wear" to prevent deterioration. Painting beam ends, she said, protects steel from corrosion.
