Before traffic improvement needs can be identified, an understanding of the physical, natural and sociocultural characteristics is necessary so the right improvement can be identified and evaluated. The next sections discuss a series of US 27 characteristics from an engineering and environmental standpoint.
Major intersections along the US 27 study corridor include SR 70, SR 66/US 98, SR 17 and SR 64/SR 17. As noted previously, the posted speeds range from 45 mph to 65 mph and the number of through lanes range from four to six 12-foot-wide travel lanes with existing ROW widths varying from 100 feet to 300 feet. Existing bicycle facilities consist of four to five-foot paved shoulders and keyholes1 or through bike lanes. Pedestrian facilities are limited to intermittent sidewalks within Sebring and Avon Park. Figure 11 details the existing typical sections throughout the project corridor.
