Project Background

The Town publicly opened bids for the project on January 12, 2017. Construction bid award recommendation was approved by Town Council during the February 9, 2017 Town Council meeting. 

Green Level West currently carries about 7,000 vehicles per day (vpd). In 2040, traffic models project it may carry 14,000 vpd on the western half and 21,000 vpd on the eastern half. Preliminary environmental investigations found that the widening project east of NC 540 would have little to no impact on natural or cultural/historic resources in the area.

Existing traffic signals located within the project area will be modified to reflect the roadway improvements. Traffic operations at the existing major side streets along the corridor have been evaluated and do not warrant additional traffic controls, such as traffic signals. The project adds pedestrian and bicycle facilities linking neighborhoods to local greenways, the Green Level Historic District, and other amenities.

Although the study is being administered by the Town, the Town has hired a consultant, Michael Baker Engineering, Inc., to perform the design, planning, and pre-construction activities. Construction of improvements on the eastern project segment is scheduled to begin in Spring 2017. There are no construction funds for improving the western project segment.

  • Green Level Church Road to NC 540 (western project segment): Project funded for functional design only.
  • NC 540 Interchange to NC 55 (eastern project segment): Project funded for design and construction.

Some benefits of the project:

  • Additional roadway capacity for Cary commuters, resulting in less traffic congestion, reduced emissions, and savings in time and fuel for motorists
  • Continuation of sidewalks along the corridor, which will improve pedestrian connectivity The roadway will have wide outside lanes to accommodate experienced cyclists, which allows residents to use alternative modes of travel other than the automobile.   *Green Level West Road is part of NC Bike Route 2, the Mountains to Sea Route that runs from Manteo to Murphy.
Based on results of the Traffic Forecast and Capacity Analysis reports, widening the western segment of Green Level West Road between Green Level Church Road and NC 540 is not anticipated to be necessary to accommodate 2040 traffic volumes. The results from the traffic forecast project volumes of less than 14,000 vehicles per day (vpd) in 2040, which suggests that the roadway will not require widening by the year 2040 as the existing two-lane section will be sufficient.  Due to the results of the Traffic Forecast and Capacity Analysis reports, the Town will not move forward with final design plans of the western segment (U-5500A) at this time, and will only complete a functional alignment for this section. 

Project Scope

The project consists of widening the eastern segment of Green Level West Road from the newly-constructed northbound ramps located at the Western Wake Freeway (NC 540) interchange to NC 55 Highway. The existing roadway is primarily two lanes in width. The project will widen the roadway to a four-lane, median-divided section with curb and gutter, sidewalks, street lighting, and wide outside lanes for cyclists, as indicated on the Town’s Comprehensive Transportation Plan. The roadway from NC 55 Highway to Glenmore Road is predominantly already widened to five lanes, so improvements along this stretch of roadway will be minimal, consisting primarily of resurfacing and pavement markings.

Project Cost and Schedule

Construction bids for the eastern segment were opened on January 12, 2017. Construction has started as of May 2017 and expected to be completed by the Fall 2018.

Design: $1 million 

The design of the Green Level West project is funded through a cost sharing program between the Town and the Capital Area Metropolitan Planning Organization (CAMPO) Locally Administered Projects Program (LAPP).

Right-of-Way / Construction: $13 million

The November 6, 2012 Community Investment Bonds referendum specifically supports right-of-way acquisition and construction of the Green Level West project.

The Town has hired an engineering consultant team to complete the environmental and design phases of the project, which is currently underway. The design includes: traffic studies, environmental assessments, development of alternatives for the widening, final plans, specifications, and cost estimates. While the project team will look at widening alternatives for Green Level West Road from NC 55 to Green Level Church Road (western segment), the construction project will be limited from NC 540 to NC 55 (eastern segment). 

Final Design Completed

Final plans were completed and approved by NCDOT in fall 2016.

Right of Way Acquisition

Right of way acquisition was completed in summer 2016.


Construction bids for the eastern segment were opened on January 12, 2017. Construction is scheduled to start in spring 2017 and expected to be completed by the end of 2018.

Construction Update:  April 2018

Median construction and paving have been completed. We are working on final clean-up before opening the road to the final traffic pattern.

Construction Update:  February 2018

Most of the paving has been completed. Construction is focused on completing the medians, which includes landscaping and brick.

Construction Update: October 2017

Construction is continuing on the new westbound lanes. Waterline installation is finishing up on the north side of the road and earth grading is continuing.

Construction Update: Mid-August 2017

Earthwork and storm drain pipe installation are finishing up in phase 1.  Paving continues in the new eastbound lanes. Recently curb and gutter and sidewalk installation has begun.

Construction Update: August 2017

As of the week of July 31, paving of the new eastbound lanes has begun and will continue throughout the month of August.

Construction Update: June 2017

Rough grading is mostly complete on the south side of Green Level West Road. Over the next month the main construction operation will be storm drain installation.
