The repair or replacement of a state bridge deemed structurally deficient, as defined in RCW
47.04.010, is exempt from compliance with this chapter as long as the action occurs within the existing right-of-way, except that the repair or replacement may occur outside the existing right-of-way as needed to meet current engineering standards or state or local environmental permit requirements for highway construction as long as the repair or replacement does not result in additional lanes for automobiles. The issuance of applicable state and local agency permits or approvals associated with the repair or replacement of such bridges is also included in this exemption from compliance with this chapter.
