Improvements to NC 16 (Brookshire Boulevard) from North Hoskins Road to I-77
Mecklenburg County
FS-1510A
I. General Description
This feasibility study describes the improvements of NC 16 (Brookshire Boulevard) from North Hoskins Road to I-77 Interchange in Mecklenburg County, North Carolina. The length of the project corridor is approximately 2.4 miles. The project area is located in the city of Charlotte. The project location is shown on Figure 1.
The existing geometry of Brookshire Boulevard is six-lanes with a narrow raised median with curb and gutter and sidewalks on both sides of the road from North Hoskins Road to I-85 interchange. There are several at grade intersections.
The existing interchange at I-85 and NC 16 (Brookshire Boulevard) is a single point
urban interchange (SPUI). NC 16 (Brookshire Boulevard) carries four-lanes across. Brookshire Boulevard east of I-85 is four-lanes with a narrow raised median. It has
curb and gutter from I-85 to just east of Centre Street. There is a sidewalk on the south side of NC 16 (Brookshire Boulevard).
The section from Centre Street to I-77 is four lanes with a variable width raised
median from Centre Street to east of Idaho Drive. There is a grassed median from east of Idaho Drive to I-77.
The current posted speed limit is 45 mph north of Idaho Drive and 55 mph south
of Idaho Drive. The proposed speed limit is 55 from I-85 to I-77. There is commercial and residential property as well as Johnson C. Smith University located near I-77.
The recommended geometry is described below.
Section A - North Hoskins Road at NC 16 (Brookshire Boulevard): Recommending
a six-lane divided variable width median with curb and gutter and sidewalks on both sides.
Section B - I-85 at NC 16 (Brookshire Boulevard): Convert the existing Single
Point Urban Interchange (SPUI) to a diverging diamond interchange (DDI) with six-lanes. Pedestrian access across the bridge will be through the median.
3
Section C - NC 16 (Brookshire Boulevard) between I-85 and new interchange location: Six-lane divided variable width median on NC 16 (Brookshire Boulevard). New location partial clover interchange with roundabouts connecting to Voncannon Drive on the south and Pennsylvania Avenue on the north. A two lane tunnel lane will connect the properties on the north and south of NC 16 (Brookshire Boulevard).
Section D - NC 16 (Brookshire Boulevard) from tie-in of new interchange to I-77: Six-lane divided variable width median on NC 16 (Brookshire Boulevard) that ties to existing at I-77. A noise wall will be constructed on the north side to reduce noise to the residential area North of NC 16.
Section E - Beatties Ford Road: Widen Beatties Ford Road to four-lane variable width raised median with curb and gutter and sidewalks on both sides. There are two dual lane roundabouts on the north and south side.
The City recommends deleting Section E. The City plans for a Streetcar Line and any work along Beatties Ford Road should be considered in the City’s project which is currently unfunded. We have removed the cost of Section E from the project cost. However, if the City of Charlotte does not implement their proposed Beatties Ford Road improvements prior to this project’s implementation, the cost of Section E will have to be included.
This is the initial step in the planning and design process for this project and is not the product of exhaustive environmental or design investigations. The purpose of this study is to describe the proposed project including cost, and to identify potential problems that may require consideration in the planning and design phases.
Once a candidate project is identified for funding in the TIP, the Feasibility Study
is followed by a rigorous planning and design process that meets the requirements of the National Environmental Policy Act (NEPA), where either an Environmental Impact Statement (EIS) or an Environmental Assessment (EA) is done.
II. Background
The purpose of this project is to upgrade NC 16 (Brookshire Boulevard) to improve the traffic safety and operations to highway standards along NC 16 in Mecklenburg County, North Carolina.
The project area is located in the City of Charlotte. NC 16 is classified as a Other
Principal Arterial from I-85 to Idaho Drive and Other Freeway from Idaho Drive and I-77.
There are several State Transportation Improvement Program (STIP) projects within the proposed study area of FS-1510A.

B-5792: Replace Bridge 342 over Andrill Terrace Street and Irwin Creek on NC 16 southbound
I-3311: I-77 from I-277 (Brookshire Freeway) to SR 5544 (West Catawba Avenue, Exit 28). Add Additional lanes.
I-5405: I-77 from I-277 to W Catawba Avenue. Construct HOT lanes and convert HOV lanes to HOT.
I-5718: I-77 from I-485 to I-277/NC 16 (Brookshire Freeway) (Exit 11). Widen existing Freeway to 10 lanes by constructing managed lanes.
I-5796: I-85 from 0.1 mile north of SR 5901 (Billy Graham Parkway) to 0.3 mile north of NC 16 pavement rehabilitation
There are three bridges in the project study area. Please see Table 3 for detailed bridge information.
III. Traffic and Safety
Currently there are two existing traffic signals located along the project corridor. The signals are located at N. Hoskins / NC 16 (Brookshire Boulevard) and I-85 / NC 16 (Brookshire Boulevard). There is a flashing light located at Idaho Drive / NC 16 (Brookshire Boulevard).
The existing 2015 Average Daily Traffic (ADT) along NC 16 (Brookshire Boulevard) varies between 53,800 vpd to 61,600 vpd between I-77 and I-85. The volume varies between 50,500 vpd to 53,100 vpd between I-85 and North Hoskins Road. For the design year 2040, the traffic volume is expected to be along NC 16 (Brookshire Boulevard) varies between 67,600 vpd to 69,200 vpd between I-77 and I-85. The volume varies between 67,200 vpd to 69,900 vpd between I-85 and North Hoskins Road. Truck traffic on NC 16 (Brookshire Boulevard) is estimated to make up approximately 6 percent of the daily traffic. The truck traffic between I-85 and North Hoskins is expected to be 11 percent of the daily traffic.
The following table shows the Level of Service for the signalized intersections. The
no build scenario has a SPUI at I-85 and NC 16. NC 16 has four through lanes. The build scenario adds one lane in each direction and a DDI at I-85 and NC 16. This will provide a six lane section from I-77 to North Hoskins Road. There are two locations of a northbound auxillary lane from I-77 to the off ramp at Beatties Ford Road and from the new interchange to I-85.

The analysis found that the DDI will operate at a better level of service in 2040.
In order to get a passing level of service at the intersection of North Hoskins Road and NC 16, several improvements will be required. North Hoskins will need an additional right turn lane on the Northeast approach. NC 16 will need additional exclusive right turn lanes on both approaches.

VII. Recommendations
The recommended improvement is widen NC 16 (Brookshire Boulevard) to six-lane divided freeway from I-85 to I-77. Widen Brookshire to a six-lane divided expressway from N. Hoskins to I-85. Convert the interchange at NC 16 (Brookshire Boulevard) and I-85 to a diverging diamond interchange. Construct on new location a partial clover
10
interchange east of Idaho Drive. Widen Beatties Ford Road to four-lane with roundabouts on the north and south side. The City recommends removing improvements along Beatties Ford Road from FS-1510A and handle any future improvements with the addition of the streetcar line or at a later date. With these improvements the facility is expected to have a level of service D or better in the year 2040.
