Earth Slopes (No Frontage Roads) This configuration, as shown in Figure 1.42 is the default grade separation configuration. This configuration shall be used where right-of-way is available, or could reasonably be made available, to accommodate 3:1 or similar embankment slopes and no parallel frontage roads are required.
quality-of-life impacts at numerous at-grade crossings. Grade separations are the most effective long-term solution, though they are challenging to implement in developed areas due to limited right-of-way, construction disruptions, and high costs. To address these challenges, the City of Fort Worth has identified 25 high-priority railroad grade separation projects and is pursuing a coordinated strategy of targeted grade separations—both converting existing at-grade crossings and constructing new ones—alongside strategic funding and collaborative partnerships with freight stakeholders to reduce congestion, improve safety, enhance neighborhood livability, and strengthen the reliability of freight movement throughout the region. The priority grade separations are shown in Figure 1.41 and Table 1.3. Further, this section establishes typical footprint requirements for these locations to support long-term right-of-way preservation. These footprints reflect structural and operational considerations — including bridge depth, vertical clearance, approach grading, drainage, and the presence or absence of frontage roads — and are intended to guide long-range right- of-way planning. They are not site-specific design templates. Specific designs, phasing, and funding strategies are developed through future project development in coordination with TxDOT and railroad partners. Two typical configurations are established in the figures that follow.
