Like you, I’ve been wondering what the county has been doing for us with the Penny Tax that passed years ago. Outside of a roundabout on Kennerly Road near Riversprings Elementary, that’s about all I see – from the county.
After seeing all the work ramping up at the state level from DOT , I decided to check locally today with the county. Glad I did, apparently “things have changed”. The project has been “descoped” and those changes were approved by Richland County Council.
Appears cost overuns is a primary reason for the change from an article from last year that sheds some light.
In any event, here was the update I saw this afternnon before calling to speak with Michael Niermeier, Director, Department of Transportation with Richland County Government.
A description of the “descope” is below and also can be seen by clicking here.
BROAD RIVER RD. WIDENING
Original Project Scope
The project scope for the Broad River Road Widening Project was to widen the roadway to 5
lanes between Royal Tower Drive and Dutch Fork Road in the Irmo community. In addition, the
road was to be widened to 3 lanes between Dutch Fork Road and I-26 (Exit 97).
(2) 4-foot wide bike lanes and (2) 5-foot wide sidewalks are included in the project scope.
Revised Project Scope – Based on traffic volumes, public input, and funding, the PDT recommended to
only include the widening from North Royal Tower to Dutch Fork.
Referendum Funding – $29,000,000.00 Current Cost Estimate: $39,663,756.37
Traffic Analysis and Results
The traffic study evaluated 15 intersections along the length of this project along with the
intersections of the offon ramps of I-26. SCDOT plans to widen I-26 in this area, so the offon
ramps would be addressed with their project.
The 2043 Level of Service in this corridor has been identified as “Adequate” for the proposed
improvements while the 2043 “No- Build” evaluation showed that the majority of the
intersections would operate at a “F” Level of Service. The recommended proposed
improvements from the traffic study are to improve the intersections by increasing turning bays.
Crash Data between 1/1/13 and 12/31/15 (3 years) shows that there were 161 crashes near these
15 intersections with the majority being rear-end collisions.
Public Input Results
185 residents attended the December 15, 2016, Public Meeting
The design alternative supported by the most residents was a 5 lane travel way that included 2 4-
foot wide bike lanes and 2 5-foot wide sidewalks
Residents agreed that removing the 3 lane section between Dutch Fork Road and I-26 was
ROW Obtained To Date – 0 Expended To Date – $0
Possible Design Modifications to Lower Cost
Widen the road to 3 lanes (2 driving lanes and a median) and also provide turning lanes at the
intersections that are missing them at this time. This could improve turning movements in and
out of the many businesses in the corridor and decrease the number of rear-end collisions.
New Approx. Estimate: $30M (Approx. Savings $9.6M)
Note: This option would not improve capacity but would improve safety and would improve
flow since left-turning vehicles would be able to pull into the median instead of block the
flow of traffic.
The cost estimate includes approximately $1,150,000 to relocate a 54” waterline at SCDOT’s
request. Staff is currently working with SCDOT to possibly have this requirement removed.
