Why Build Roundabouts?
Stargell/5th Street
Stargell/Mariner Square Loop
Roundabout Phasing Approach
Phase 1 (2027-28):
• Build full corridor improvements plus Stargell/5th
Street roundabout
• Use modular materials, capture safety benefit
• Full construction at corners, with modular
construction in the middle of the circle
Phase 2 (2029+):
• Build Stargell Ave/Mariner Sq Loop, when funds
available
• Upgrade Stargell Ave/5th St with landscape and
green infrastructure, when funds available
Phase 2: Stargell/Mariner Square Loop
Phase 1: Stargell/5th Street
Opportunities for cost savings while
achieving safety benefit
• Permanent corners & ADA ramps
• Lower-cost materials at medians
and round center circle
