MD 140/I-695 Interchange Website
Welcome Background The Project Urban Diamonds Project Information
The proposed construction will improve traffic flow on MD 140 through the interchange, upgrade the MD 140/I-695 interchange from its current configuration to a single-point, urban diamond interchange, and raise the elevation of the bridge slightly to allow for any future Beltway widening. The present bridge spans 8 lanes of traffic on the Beltway. The new bridge will allow 10 lanes to pass underneath if and when the Beltway is ultimately widened in this area. The new bridge will be slightly higher, bringing the clearance over the Beltway up to current interstate highway standards.
MD 140 and the ramps to and from I-695 will be reconstructed to improve roadway geometry, improve sight distances, and increase vehicle storage lane lengths for right and left turn movements. Although the number of through lanes on MD 140 will remain the same with two in both directions, the number of left turn lanes for traffic turning from MD 140 onto I-695 will be increased to provide two lanes in both directions. Additionally, a third northbound lane will be provided on MD 140 from the Commerce Center entrance to Woodholme Center Circle.
This project will take measures to preserve and protect the environment. New stormwater management facilities will provide quantity and quality control of roadway runoff. Reforestation will follow construction to compensate for the loss of trees during the project. The SHA will install devices to protect streams and wetlands from sediment pollution during construction.
In accordance with SHA's vision to create facilities that are more than merely functional, urban streetscape elements have been incorporated into the design of the MD 140 corridor. These elements include: medians with trees, various plantings or brick paving blocks; new sidewalks on both sides of the roadway; brick paving block trim next to the curbs; and green landscaped buffers between the sidewalks and the roadway. The bridge itself will include decorative parapet walls with black iron railings and accent lighting. These measures will create an attractive boulevard appearance. The streetscape elements that are included in the MD 140/I-695 interchange improvement project provide continuity with the current SHA streetscape project for MD 140 just south of this location. SHA is currently constructing improvements in the adjacent segment of the MD 140 corridor between the southern limit of the MD 140 interchange improvement project and Glengyle Avenue at the Baltimore City line.
