Bridge No over the Spokane River at State Line (looking south) 1 of 19

Objectives of Project Ensure safety of the traveling public Minimize impacts to the environment and the traveling public Expedite Design, Environmental Permitting, Right of Way and Construction time to replace the existing bridge before it fails and an unplanned bridge closure is required Construct an Economical, Functional and Aesthetically pleasing project which meets the demands of motorized and trail users today and in the future Partner with State and County Parks Departments to eliminate the Centennial Trail at-grade crossing and minimize Park land impacts Utilize modern bridge methods with longer spans to construct a bridge with fewer piers in the Spokane River to “open up” the waterway 2 of 19

Existing Bridge Facts Built in 1939 (69 years old) 512 ft. long Originally 48 ft. wide, but currently restricted to 26 ft. (2- 11 ft. lanes with 2 ft. shoulders) Currently has weight restrictions of 10,000 lbs or less (cars and pickup trucks only) Deteriorating concrete Cracked hinges Piers in river flow Footing is undermined at river pier Inspection frequency increased to 1 year due to condition of bridge 3 of 19

Proposed Bridge Information On same alignment as existing bridge 480 ft. long 32 ft. wide roadway with 10 ft. wide ‘Shared Use’ trail (2- 12 ft. lanes with 4 ft. shoulders) Centennial trail rerouted to pass under south end of bridge Piers at edge of river “opens up” waterway Road closed with alternate routes during construction Built over 2 construction seasons 13 of 19

Road Closure The preferred alignment for this project will require closing the road for a period of approximately 18 months The following is a list of services which could be affected and how the impacts to the public will be addressed or mitigated: Emergency Services –Fire Department -The area north of the river will be served by the Spokane Valley Fire Department, Station #3 located on North Harvard Road and Station #4 on East Wellesley –Ambulance Service -AMR Ambulance Company has been informed of the proposed closure of the bridge School Districts –School buses from Central Valley and East Valley do not use bridge on regular routes Postal and Delivery Services –Postal and delivery services do not use bridge currently Garbage Collection –Garbage trucks can not use bridge currently Alternate routes around the project area are presented at the end of slide show 14 of 19
