The John F. Kennedy Memorial Highway (I-95) carries more than 160,000 cars each day between points in Baltimore and the north and east.  With traffic volumes increasing every year and expected to grow by at least 35-40% over the next twenty years, the Maryland Transportation Authority (MdTA) selected JMT to provide preliminary design and support services for multiple options along this nine mile corridor between I-895 to north of MD 43.  Elements of this work task included.

• Minimize impacts on communities and the environment.
• Development and analysis of multiple concepts for General Purpose and Managed Lanes for I-95’s mainline.
• Evaluated multiple line and grade options for the I-95 interchanges with I-695, I-895 and MD 43.
• Re-designed the existing double-braid shaped directional I-95 interchange with I-695 to a fully directional, multilevel design eliminating the current left lane ramp configurations.
• Minimize impacts to the existing right-of-way and utilities.
• JMT performed traffic counts and developed travel demand forecasts for the various alternatives.
• Performed capacity and operational analyses, studied maintenance of traffic options and constructability issues, and evaluated impacts to signing, lighting and ITS systems.
• Prepared preliminary layouts of bridge structures, retaining walls, and noise walls in a complex network of multilevel interchange designs at the I-695, I-895 and MD 43 interchanges and construction phasing to maintain traffic at all times.
• JMT presented the alternatives to agency officials and the public using a variety of visual tools such as renderings to show construction phases and computer animation to demonstrate new traffic patterns.  With JMT’s assistance, MdTA was able to recommend which interchange alternatives would move forward into final design.
