Expressways are a design type of principal arterials. A street or highway designed to both carry traffic and provide access to abutting property. Cross traffic is accommodated at at-grade intersections without signals for streets with low traffic levels. The primary purpose of the minor arterial is to serve moderate length neighborhood trips and to channel traffic from collectors and local streets to principal arterials or expressways. A street or highway designed to carry traffic and provide access to abutting property.
Cross traffic is accommodated at at-grade intersections with local streets.
No signals are provided. The primary purpose of the collector is to serve short length neighborhood trips and to channel traffic from local streets and abutting properties to minor arterials and principal arterials. A street or rural road designed to provide access to abutting property and only incidentally channel traffic short distances to collectors or minor arterials. The typical trip begins on a local trip and ends on a local street. On the state trunk highway system, where traffic carrying capacity is of primary concern, the response to loss of performance and carrying capacity due to development allowed by local government land use decisions has been to relocate the highway as a bypass.
