Section 6G.16 - Crossovers
Universal Citation: 2 DE Admin Code 6G.16
Current through Register Vol. 28, No. 3, September 1, 2024
Guidance:
01 The following are considered good guiding principles for the design of crossovers:
A. Tapers for lane drops should
be separated from the crossovers, as shown in Figure 6H-39.
B. Crossovers should be designed for speeds
no lower than 10 mph below the posted speed, the off-peak 85th-percentile speed
prior to the work starting, or the anticipated operating speed of the roadway,
unless unusual site conditions require that a lower design speed be
used.
C. A good array of
channelizing devices, delineators, and full-length, properly placed pavement
markings should be used to provide drivers with a clearly defined travel
path.
D. The design of the
crossover should accommodate all vehicular traffic, including trucks and buses.
Support:
02 Temporary traffic barriers and the excessive use of TTC devices cannot compensate for poor geometric and roadway cross-section design of crossovers.
