MD 0295 BALTIMORE WASHINGTON PARKWAY MD 100 TO I-195 AND HANOVER ROAD
When will this impact me?
MD 295, Baltimore Washington Parkway
Location of Project:
MD 100 TO I-195 AND HANOVER ROAD
Study to widen MD 295 from 4 to 6 lanes from MD 100 to I-195 including an interchange at Hanover Road and improvements to Hanover Road from the CSX railroad tracks in Howard County to MD 170 (3.27 miles).
Project Planning Study - The purpose of this project is to improve the existing capacity, traffic operations and safety of MD 295 as well as to enhance Hanover Road as a secondary access to Baltimore Washington International Thurgood Marshall Airport (BWI) and the surrounding areas.
What is under study:
The following describes the Alternatives Retained for Detailed Study (ARDS):
Mainline Widening: MD 295 would be widened from a four-lane roadway (two through lanes in each direction) to a six-lane roadway with three through lanes in each direction. The additional width would be constructed within the median of MD 295 in each direction, from south of the MD 100 interchange to north of the I-195 interchange.
Alternative 1: No-Build: Alternative 1 includes no major improvements to the existing roadway. Improvements would occur as part of the routine maintenance and safety improvements determined for the project area. While the No-Build Alternative does not address the Purpose and Need for the project, it does serve as the baseline for comparing the impacts and benefits associated with the other build alternatives.
Alternative 3: Compressed Diamond Interchange: Alternative 3 proposes a compressed diamond interchange at MD 295 and Hanover Road. Ramps to and from MD 295 would meet Hanover Road at a signalized intersection on either side of MD 295.
Alternative 4: Single Point Urban Interchange (SPUI): Alternative 4 proposes a single point urban interchange (SPUI). While similar to traditional diamond interchanges, SPUI ramps curve inward and meet at a single traffic signal below or underneath the bridge, allowing opposing left turning movements to occur simultaneously.
Alternative 7: Loop and Half Diamond Interchange with the southern alignment of Hanover Road at MD 295: With this interchange a loop ramp is proposed in the southwest quadrant and one-way directional ramps are proposed in both the northeast and southeast quadrants. No ramps are proposed in the northwest quadrant of the interchange. The alignment of Hanover Road would be shifted to the south of its current alignment as it crosses MD 295 as part of this interchange.
Alternative 8: Diverging Diamond Interchange: The Diverging Diamond Interchange switches traffic, at the ramp terminals, over to the opposite side of the roadway within the interchange. This promotes left-turn movements and eliminates the left-turn signal phase improving the interchange’s efficiency. This traffic pattern improves capacity and minimizes the length of the queues which could cause failing operating conditions within a diamond interchange.
Option 2: Hanover Road South Option: The Hanover Road South Option proposes to minimize the number of curves along Hanover Road and relocates the Hanover Road and Ridge Road intersection approximately 300 feet south of the existing location.
In addition to the ARDS described above several new options have been developed that will be carried forward into detailed study.
Alternative 3 - Option A: This alternative utilizes the same interchange configuration as Alternative 3; however, it shifts the alignment of Hanover Road approximately 300 feet to the south at the interchange with MD 295 similar to Alternative 7.
Alternative 4 - Option A: This alternative utilizes the same interchange configuration as Alternative 4 and uses the same shift of Hanover Road to the south at the interchange with MD 295 as Alternative 3 - Option A.
Option 2 and 2A at MD 170 and Stoney Run Road: These options add direct access ramps to and from MD 170 (Aviation Blvd.) to Stoney Run Road.
