Stewart Street Roundabout
22
Preferred Option- Single lane
roundabout with northbound
and southbound bypasses
Design highlights:
LOS A for all legs and all times
except westbound PM peak
2040 scenario.
Decreased O&M costs
Improved safety- Significant
anticipated crash reduction
from 3/year to 1.6/year
(Societal cost savings of
$2.8M)
Single lane roundabout =
easier to navigate
Provides gateway to the City
