Alternative I - No Build Alternative
(Existing plus Committed Projects)
|
Alternative I generally involves the following improvements:
- Existing general purpose lanes to reamin (no additional lane widening)
- Major cross streets will continue to be signalized
- Includes committed transporation improvement projects, as identified in the
Capital Area MPO Long-Range
Transportation Plan (LRTP)
- Bicycle lanes or sidewalks are not possible along US 1
|

Alternative II - Highway Alternative
|
Alternative II generally involves the following improvements:
- Eight or more lanes from I-540 to NC 98
- Six general prupose lanes from NC 98 to US 1A North in Franklin County (median barrier, no corss access points
- Interchanges at major cross streets
- Two-lane frontage roads (either one-way or two-way) paralleling US 1 or
backage roads set behind adajacent properties to provide access
- Implement
freeway
standards where practical
- Implement
expressway standards with
partial control of access
where freeway standards are not practical
- Bicycle lanes and sidewalks along frontage/backage roads and cross streets
- Park and ride lots and transit stops on frontage or backage roads
|

Preliminary Preferred Alternative
Alternative IIIA - Highway + Transit Alternative
Two-way Frontage or Backage Roads
|
Alternative IIIA generally involves the following improvements:
- Six general purpose lanes from I-540 to US 1A North in Franklin County (freeway standards)
- Space for either two special use/high-occupancy vehicle (HOV) lanes or two general purpose lanes,
one in each direction from I-540 to the NC 98 Bypass
- Two-way, two-lane frontage roads with a center turn lane paralleling US 1 or
backage roads set behind adjacent properties to provide access
- Interchanges at major cross streets
- Grade-separated cross streets to provide multi-modal east-west connectivity
- Bicycle lanes and sidewalks along frontage or backage roads and cross streets
- Park and ride lots and transit stops on frontage or backage roads
|

Alternative IIIB - Highway + Transit Alternative
One-way Frontage Roads & Two-way Frontage or Backage Roads
|
Alternative IIIB generally involves the following improvements:
- Six general purpose lanes from I-540 to US 1A North in Franklin County (freeway standards)
- Space for either two special use/high-occupancy vehicle (HOV) lanes or two general purpose lanes,
one in each direction from I-540 to the NC 98 Bypass
- One-way, two-lane frontage roads paralleling US 1 from I-540 to the NC 98 Bypass to conserve right-of-way
and provide access to properties
- Two-way, two-lane frontage roads with a center turn lane paralleling US 1 or
backage roads set behind adjacent properties to provide access from the NC 98 Bypass to US 1A in Franklin County
- Interchanges at major cross streets
- Grade-separated cross streets to provide multi-modal east-west connectivity
- Bicycle lanes and sidewalks along frontage or backage roads and cross streets
- Park and ride lots and transit stops on frontage or backage roads
|

Alternative IV - Highway + Reversible Special Use Lanes
|
Alternative IV generally involves the following improvements:
- Six general purpose lanes from I-540 to US 1A North in Franklin County (freeway standards)
- Two reversible special use/high-occupancy vehicle (HOV) lanes, in the center of the roadway from I-540 to NC 98
- Two-lane frontage roads (either one-way or two-way) paralleling US 1 or
backage roads set behind adajacent properties to provide access
- Interchanges at major cross streets
- Grade-separated cross streets to provide multi-modal east-west connectivity
- Bicycle lanes and sidewalks along frontage roads and cross streets
- Park and ride lots and transit stops on frontage or backage roads
