DART Shiloh

DART Shiloh – Landmark Project

The DART Shiloh project represents an important transportation infrastructure development associated with the Shiloh Road Station and the Dallas Area Rapid Transit (DART) Silver Line Regional Rail system in Plano, Texas. The Silver Line is a 26-mile regional rail corridor connecting DFW Airport with Shiloh Road in Plano and serving seven cities across North Texas. DART identifies Shiloh Road as the eastern terminus of the Silver Line.

Transportation projects such as DART Shiloh require careful coordination between structural engineering, architectural design, civil infrastructure, rail systems, passenger circulation, utilities, and construction activities. The structural components must be accurately designed, modeled, detailed, fabricated, and installed to support a facility that is expected to serve commuters and the surrounding community for many years.

From a structural steel detailing and BIM perspective, the DART Shiloh project demonstrates the value of accurate 3D structural modeling, coordinated steel detailing, connection documentation, fabrication drawings, erection drawings, and quality-control procedures.

Regional Transportation Infrastructure

The DART Silver Line is designed to improve regional mobility and connect major employment, education, population, and activity centers throughout North Texas. The line extends between DFW Airport and Shiloh Road and crosses three counties and seven cities.

Shiloh Road Station

Shiloh Road Station provides an important connection within the Silver Line network. DART’s station information identifies the facility as part of the regional rail system and notes connections with DART’s broader transit network and GoLink on-demand service.

Multimodal Transportation Connectivity

A modern rail station must coordinate multiple forms of transportation and passenger movement. Pedestrian routes, buses, on-demand transportation, parking, sidewalks, rail platforms, and surrounding streets all contribute to the station environment.

Supporting Regional Mobility

The DART Shiloh project therefore represents more than an individual station structure. It forms part of a larger transportation system intended to improve access throughout the Dallas-Fort Worth region.

Structural Engineering for DART Shiloh

Structural engineering is fundamental to the development of a safe, durable, and constructible transportation facility. The structural system must accommodate passenger areas, platforms, station elements, canopies, circulation components, architectural features, and associated infrastructure.
