The project team designed nine preliminary alternatives to meet specific project goals. Each alternative went through a screening process to determine if they met the project’s goals. Four alternative project designs met the majority of the Tier One (first round) goals and moved forward for further analysis. You can review the Tier One Project Goals/Screening Metrics here.
Alternative A meets the following Tier One project goals:
Removes the alternate merge by modifying the lane designations for Sam Rittenberg Blvd. One Sam Rittenberg Blvd. lane becomes the left-turn lane at Orange Grove Rd.
Provides a signalized crossing for bikes and pedestrians at the Orange Grove Rd. and Sam Rittenberg Blvd. intersection and at new traffic signal at the Sumar St. and Sam Rittenberg Blvd. intersection.
Extends Sumar St. from Sam Rittenberg Blvd. to Orange Grove Rd. including bike and pedestrian accommodations to create additional connectivity. This provides more options for travel in the study area network including a more direct connection for school traffic to Sam Rittenberg Blvd. and additional walking and biking options to access residences and businesses in the study area.
Maintains full access in all directions to Southgate Dr.
Improves the level of service for vehicles at the Orange Grove Rd. and Sam Rittenberg Blvd. intersection.
Alternative A does NOT meet the following Tier One project goals:
Does not maintain full access at North Bridge Dr. (right-in, right-out operations only)
Does not maintain existing access to businesses along SC 7 for northbound traffic (towards I-26)
Does not provide equal or better level of service for vehicles at the intersections along Sam Rittenberg Blvd.
Does not provide equal or better level of service for vehicles at the intersections along Old Towne Rd.
Directional Traffic flow Patterns
Sam Rittenberg Blvd. to I-26: Two lanes merge into the outside lane of Sam Rittenberg Blvd. to continue Northbound
I-26 to Sam Rittenberg Blvd.: Two lanes continue straight Southbound
Old Towne Rd. to I-26: Two lanes continue straight Northbound
I-26 to Old Towne Rd.: Two lanes continue straight to a traffic signal (same as current Southbound movement) then continue Southbound
