Scope Of Work
The I-270 at Watkins Mill Road Interchange project is an $85 million project for the Maryland State Highway Administration to relieve congestion on one of Montgomery ’s most congested corridors. Construction plans include a new interchange on I-270 consisting of 14 structures, including a five span bridge over I-270 and a two span bridge along an off-ramp.
KEY CHALLENGES & PROJECT DETAILS
As part of the project scope, the relocation of approximately one mile of 48” waterline and 16” sewer line will be relocated.
In addition to the main structures, the project features two box culverts, a 72” storm drain, and numerous cast-in-place and MSE retaining walls.
Extremely environmentally sensitive, the project includes the complete reconstruction of a tributary of Seneca Creek, which extends for over a mile throughout the project limits.
