Opening Year Alternative
Opening Year Alternative
Original Design
Opening Year Alternative
• Traffic volumes were developed for the opening year.
• Bottom line - not able to reduce the number of thru lanes.
• Under current design, left turns are not permitted at the two
major intersections (Arborway/South St & Arborway/Washington
St)
• Evaluated allowing left turns during the off-peak hours - two
concepts
• Concept 1 allows EB & WB left turns at the 2 intersections
• Concept 2 allows the WB left to occur at the intersection of
Arborway/Washington St in the bus only lane.
Opening Year Alternative
Concept 1
Concept 1 degrades
overall traffic operations,
and requires a significant
amount of additional
signage and technical
equipment.
OFF-PEAK ONLY
Opening Year Alternative
Concept 2
Concept 2 is easily
implemented and did not
significantly degrade traffic
operations.
Operations and Maintenance Plan
O&M Plan Overview
• Three plans developed based on anticipated
need:
– Snow and ice removal
– Operations and Maintenance
– Police Jurisdiction
• Continue to discuss and refine
