Washington Revised Code Title 47. Public Highways and Transportation § 47.50.010. Findings--Access

(a) Regulation of access to the state highway system is necessary in order to protect the public health, safety, and welfare, to preserve the functional integrity of the state highway system, and to promote the safe and efficient movement of people and goods within the state;

(b) The development of an access management program, in accordance with this chapter, which coordinates land use planning decisions by local governments and investments in the state highway system, will serve to control the proliferation of connections and other access approaches to and from the state highway system. Without such a program, the health, safety, and welfare of the residents of this state are at risk, due to the fact that uncontrolled access to the state highway system is a significant contributing factor to the congestion and functional deterioration of the system; and

(c) The development of an access management program in accordance with this chapter will enhance the development of an effective transportation system and increase the traffic-carrying capacity of the state highway system and thereby reduce the incidences of traffic accidents, personal injury, and property damage or loss; mitigate environmental degradation; promote sound economic growth and the growth management goals of the state; reduce highway maintenance costs and the necessity for costly traffic operations measures; lengthen the effective life of transportation facilities in the state, thus preserving the public investment in such facilities; and shorten response time for emergency vehicles.

(a) The access rights of an owner of property abutting the state highway system are subordinate to the public's right and interest in a safe and efficient highway system; and

(b) Every owner of property which abuts a state highway has a right to reasonable access to that highway, unless such access has been acquired pursuant to chapter 47.52 RCW, but may not have the right of a particular means of access. The right of access to the state highway may be restricted if, pursuant to local regulation, reasonable access can be provided to another public road which abuts the property.
