Preliminary Study of this concept shows improved traffic operations and
added safety benefits
o
South leg of Quaker Road would receive all eastbound traffic
o
North leg of Quaker Road would receive all westbound traffic
o
Vehicle paths no longer crossing
o
Promotes continuous flow of vehicles
o
Longer queue length on South Greeley during heavy peak periods
•
Requires reconfiguration of curbing, striping and crosswalks
•
Loss of approximately 6 parking spaces on NB South Greeley Avenue
•
Curbs at triangle corners would also need to be mountable or eliminated
•
Estimated DOT and County Review Time = 6 to 8 weeks ±
•
