Feb. 8, 1983 BIKEWAYS -23- • J. AT-GRADE RAILROAD CROSSINGS Oli \\ Additional Whenever it is necessary to cross railroad tracks 0 00 \ fred./W with a bikeway, special care must be taken to assure that 011 the safety of bicyclists is protected. The bikeway crossing IIII 0 \V should be at least as wide as the approaches of the bike- : \o way. Whenever possible, the crossing should be straight, • ,) and at right angles to the rails. For on-road bikeways, : \ \ where a skew is unavoidable, the shoulder should be widened, if possible, to permit bicyclists to cross at right la angles. (See Fig. I). Special construction and materials III I should be considered to keep the flangeway depth and • width to a minimum. Pavement should be maintained, ! Bikeway so ridge buildup does not occur next to the rails. In some • cases, timber plank crossings can be justified, and can provide for a smoother crossing.Where hazards to bicyclists • \ \ cannot be avoided, appropriate signs should be installed gla \ Standard to warn bicyclists of the danger. For off-road bikeways, • ■ curve it is also desirable to cross at 90°. see Fig. J. When it is widening I not possible to cross at 90 the bikeway should be widened • to allow the cyclist to cross at as close to 90° as possible, 0 see Fig. K. • • • -■-- Roadway c.
