Washington State City Street and Road Standards
Contents
Introduction to Street and Road Standards
Chapter 35.78 RCW requires cities and counties to adopt uniform definitions and design standards for municipal streets and roads. Standards for arterials are set through RCW 35.78.030 and RCW 35.78.040 by a state design standards committee in cooperation with the Washington State Department of Transportation (WSDOT). These uniform design standards apply to all new construction on major arterial and secondary arterial roads and streets and to reconstruction of old such roads and streets as far as practicable. No deviation from the adopted design standards may be made without approval of the state aid engineer.
