CATS LYNX Blue Line Light Rail “First to Ride” Grand Opening

SEPI’s involvement on the signature Blue Line Extension project spans design to construction.

The Charlotte Area Transit System (CATS) LYNX Blue Line is the first light rail service in the Charlotte metro area. The 18.9-mile long track operates from I-485 at South Blvd to UNC Charlotte’s main campus.

The new CATS LYNX Blue Line Extension project spans 9.3-miles from 7th Street Station in Uptown Charlotte through the NoDA (North Davidson) and University areas.

SEPI staff provided pedestrian connectivity design, surveying, site/civil, traffic engineering, and construction engineering and inspection through multiple project phases.

Pedestrian connectivity design

SEPI designed bicycle and pedestrian facilities utilizing NACTO guidelines for Segment C of the CATS LYNX Blue Line corridor. Connectivity for various modes of transportation are integrated with the 1.3-mile, multi-lane divided roadway for improved safety and mobility. The corridor travels along existing alignment of North Tryon Street parallel to the new dual track Light Rail system from Uptown Charlotte to UNC Charlotte.

Specific SEPI design tasks included roadway and intersection design, traffic control, maintenance of traffic, signing design, pavement markings, sidewalk, and multi-use path design. [Learn More]

Survey services

For the LYNX Light Rail I-485 Station survey project, SEPI collected cross-section data along 400 feet of track. The cross-section of the rails and station were taken utilizing Robotic Total Station and high definition laser scanning.

On the CATS South Corridor Storm Drain Location project, SEPI collected horizontal and vertical data of the storm drain structures within the right-of-way of the nine-mile existing LYNX Blue Line Rail System. Field procedures were conducted to establish control points by GPS at each of the 10 train stations and various points along the nine-mile route where storm structures were located. [Learn More]

Construction inspections services

This portion of the project included 11 new light rail stations, approximately 20 at-grade street crossings, and 11 bridge structures over or under roads, railroads, and environmental features.

SEPI established an asphalt-testing laboratory and provided asphalt testing and QA/QC oversight,  concrete inspection, and density determination to meet NCDOT specifications.

Our technicians performed construction inspections under extreme traffic congestion with significant utility conflicts, often adjacent to active railroad right-of-way. Inspection of new pedestrian facilities linked to the corridor included sidewalks, multi-use trails, and bicycle lanes.

To help ensure compliance across the board, technicians monitored the review of project documentation against CATS, FTA, City of Charlotte, and NCDOT requirements. [Learn More]
