Appendix C - Interchanges and Widening

The Steering Committee considered interchanges at several locations where conditions are expected to be unacceptable in 20 years. The conclusions are listed below.

Route 40 and SR 896

Primary issues considered by the Steering Committee:

  • Safety: The combination of high speeds and high traffic levels creates a potentially unsafe condition. Recent fatal accidents have heightened concern about safety.
  • Congestion: Without improvements, intersection delay in 2020 will be three to four times greater than it is today.
  • US 301: The 301 Major Investment Study recommended not pursuing SR 896 as a freeway option for US 301 north of the Canal; WILMAPCO has adopted this recommendation.

Planned improvement highlights:

  • Safety: Immediately pursue additional interim improvements to address current safety concerns - options include improved warning devices, red light cameras, signing changes and rumble strips. These improvements should address the highest percentage of accidents at the intersection.
  • Congestion:
    • Prepare preliminary design plans, as soon as possible, for an interchange.
    • Preserve right of way for the interchange.
    • Construct interchange in Phase II (2008-2013), unless forecast conditions change significantly.

Route 40 and SR 72; Route 40 and Norfolk Southern Railroad Crossing

Primary issues considered by the Steering Committee:

  • SR 72 still experiences congestion in peak hours, even with recent improvements. Without further improvements, intersection delay in 2020 will be three to four times greater than it is today.
  • Trains crossing Route 40 create safety and congestion problems which will increase in the future.
  • A grade separation of Route 40 and SR 72 would have significant property and visual impacts.
  • Any grade separation of Route 40 and the railroad tracks must take Route 40 over the tracks.
  • The combination of grade separations at SR 72 and the Norfolk Southern railroad tracks would create a visual barrier along Route 40 more than one mile long.

Planned improvement highlights:

  • SR 72 congestion:
    • First step: Add a second through lane on SR 72 in both directions at the intersection with Route 40 in Phase I (2000 - 2007).
    • Second step: Add a third through lane on Route 40 in both directions, in association with widening of Route 40, in Phase II (2008 - 2013).

A grade separation at SR 72 was considered and rejected by the Steering Committee due to property and visual impacts.

  • Norfolk Southern railroad tracks:
    • Prepare preliminary design plans, as soon as possible, for a grade separation at the tracks.
    • Preserve right of way for the grade separation.
    • Construct the grade separation in Phase III (2014-2020), unless forecast conditions change significantly.

Route 40 & SR 7

Primary issues considered by the Steering Committee:

  • Safety:
    • This intersection had the highest number of reported accidents of any intersection along Route 40.
    • There are minimal pedestrian accommodations near the intersection.
  • Congestion: This intersection has the highest level of congestion along Route 40. Without further improvements, intersection delay in 2020 will be three to four times greater than it is today.
  • Eden Square Exit: The close proximity of the exit complicates the traffic signal operation at the SR 7 intersection, contributing to congestion.

Planned improvement highlights:

  • To address both safety and congestion issues:
    • Add a second through lane on SR 7 in both directions from Glendale Plaza to Newtown Road. Add a second left turn lane in both directions on Route 40 and on southbound SR 7. (This work is being done as part of the SR 7 improvements.)
    • Add pedestrian signals and crosswalks for crossing Route 40 near Eden Square as part of SR 7 Improvements.
    • Build a new connector road to the Eden Square Shopping Center opposite Glendale Connector on SR 7; close the Eden Square exit onto westbound Route 40 in Phase I (2000-2007).
    • Prepare preliminary design plans, as soon as possible, for an interchange.
    • Preserve right of way for the interchange.
    • Construct the interchange in Phase II (2008-2013), unless forecast conditions change significantly.

Widening of Route 40

Due to future projected traffic growth, we anticipate that Route 40 will need to be widened. Widening will consist of the addition of one lane in each direction and will typically occur to the outside of existing travel lanes. The widening will occur in phases and will provide three lanes in each direction from SR 896 to SR 1. See the phase maps for timing of the segments. The widening of the two "end" segments (the Maryland state line to SR 896 and SR 1 to Route 13) was not projected to be needed in the next 20 years.
