What Did We Discover?What Did We Discover?Issues Identified

Vehicular Travel Issues• Significant congestion during peak

commuter hours S-48 serves as the primary

connection between Chapinand I-26

• Lack of parallel routes and minimal connectivity

• “Bottleneck” at Chapin High School• Future failure of all intersections• Ninety-degree turn at western end

of Columbia Avenue

Vehicular Travel Issues• Through traffic at Chapin

town center• Offset intersection of Peak

and Clark Streets• Significant queuing where

left turns are frequent• Difficult truck

ingress/egress to Ellett Brothers

Pedestrian & Bicycle Issues• Excessive travel speeds• Lack of sidewalks and connections

between land uses• Minimal controlled

pedestrian crossings• Vehicular disregard for

pedestrian/bicycle right-of-way and safety

• Lack of elements to designate a bicycle-friendly environment

Transit Issues• SmartRide park-and-ride

lot is limited by size and perceived safety

• Lack of ped/bike connections between SmartRide park-and-ride lot and Town of Chapin

• Absence of transit to majority of corridor

Railroad Corridor Issues• Perpendicular intersection of

S-48 and railroad• Queuing of westbound traffic

waiting for trains creates difficult left-turn movement and traffic backups across rail line

• Numerous at-grade rail crossings

• Railroad corridor acts as barrier

Land Use Issues• Large amount of vacant

land with the potential to build out in a low density pattern

• Grouped incompatible uses• Lack of design standards• Eroding community

character• Existing development

Preliminary Alternatives – Vehicular TravelWhat’s Being Considered?What’s Being Considered?

Dedicated turn lanes, traffic signals, and correction of geometric deficiencies at intersecting streets

New, localized east/west linkages

New circulation and connections within Chapin High School property

New, localized east/west linkages

New circulation and connections within Chapin High School property


Potential for Redesigned Circulation and Access at Chapin High School

Preliminary Alternatives – Vehicular Travel

Widen S-48 to three lanes beginning at Chapin Road and transition to five lanes

Construct northern and/or southern connector

New interchange(s) with I-26 with appropriate roadway improvements
