SR 9 - SR 204 Intersection Improvements - Design Options

Local connectivity improvements (Concept B)
This option makes several improvements near the SR 9/SR 204 intersection, including a roundabout interchange at SR 9/SR 204 with SR 9 traveling under the roundabout to allow SR 9 traffic to flow straight through. The SR 9/SR 204 roundabout would be connected via new frontage roads to a new roundabout at the Vernon and Davies intersection. Traffic traveling to and from SR 9 to the south would use the SR 9/SR 204 roundabout, while traffic to and from SR 9 to the north would use the Vernon and Davies roundabout. A smaller roundabout would also be considered at 4th Street NE to provide full access from SR 9 to 4th Street NE.

Intersection improvements (Concept C)
This design improves access to Frontier Village via 7th Street NE by adding a cul-de-sac at Vernon Road, closing off 92nd Avenue NE, and creating an opportunity to turn right off NB SR 9 to 4th Street NE and turn right from 4th Street NE onto NB SR 9. Village Way, a locally-used roadway into Frontier Village, is improved to provide access through Frontier Village to the SR 9/SR 204 intersection.

Recessed ramp (Concept G2B)

This concept creates a direct connection from eastbound SR 204 to northbound SR 9 by constructing a ramp under SR 9 that begins on SR 204 west of 91st Avenue NE and continues along SR 204, re-emerging onto NB SR 9. The 91st Ave NE/SR 204 intersection stays at grade above the newly constructed connection on a bridge-like structure. The SR 9/SR 204 intersection is reconfigured, remaining at grade above the newly constructed connection. Other improvements include creating an opportunity to turn right off NB SR 9 to 4th Street NE and turn right from 4th Street NE onto NB SR 9, and improving Village Way as a local road through Frontier Village.

Tight diamond interchange (Concept E)
This design concept lowers SR 9 below the interchange and adds a lane to SR 9 in both directions from south of Market Place NE to the interchange and north to Lundeen Parkway. The SR 9/SR 204 intersection stays at grade with four lanes of SR 9 (two lanes each way) under the intersection. Creates on- and off-ramps in both directions of SR 9 and updates the Vernon Road off-ramp. Other improvements include signalizing the intersections at the ends of the on and off ramps, creating an opportunity to turn right off NB SR 9 to 4th Street NE and turn right from 4th Street NE onto NB SR 9, and improving Village Way as a local road through Frontier Village.

Roundabout interchange (Concept H)
This design concept is similar to the tight diamond interchange (Concept E), but does not add new lanes to SR 9. The SR 9/SR 204 intersection would be changed to an at-grade roundabout interchange with SR 9 traveling below the roundabout. This concept allows SR 9 traffic to flow through the interchange. On- and off-ramps are added in both directions of SR 9. Other improvements include creating an opportunity to turn right off NB SR 9 to 4th Street NE and turn right from 4th Street NE onto NB SR 9, and improving Village Way as a local road through Frontier Village.
