1.7.4. Typical Cross-Section Typologies (Mapped Roadway Classifications) The following figures illustrate the ultimate cross-sections used for mapped roadway classifications in the Fort Worth Master Roadway Network. Each cross-section applies to one or more functional classifications, as noted in the figure title. These cross-sections establish the minimum ROW needed to support long-term corridor development. The number of through lanes for each corridor is shown on the MRN-CR Lane Map in Figure 1.7 . For established thoroughfares, the existing lane configuration is generally considered fixed. However, the requirements for sidewalks, shared-use paths, and other multimodal accommodations must be met to the extent practicable consistent with available ROW and proportionality standards must be met. Any variation from the adopted ultimate configuration is subject to the amendment or waiver processes outlined in Section 1.10 of this chapter.
Cross-Section Typologies by Functional Class, Lane Count, and Overlay The cross-section that applies to any given corridor is determined by three factors: its functional classification, its ultimate lane count as shown on the MRN-CR Lane Map, and whether a Freight Priority Area or Compact Development Area overlay applies. Figure 1.10 illustrates this relationship. The cross-sections that follow are organized by this combination — find the figure that matches the functional class, lane count, and overlay condition for the corridor in question.
Standard travel lanes are 11 feet. Within Freight Priority Areas , travel lanes are 12 feet to accommodate heavy vehicle activity, and active transportation facilities are provided as a separated shared-use path combining bicycle and pedestrian accommodation. Within Compact Development Areas, on-street parking is provided alongside a protected on-street bike lane and a separate sidewalk — reflecting the shorter trips and higher pedestrian activity character of these districts Principal Arterials are exempt from the on- street parking CDA regulations given their regional mobility function.
