Focus Area #1 At-Grade Crossing Notes • Channelized Right-Turn onto SB400 On-Ramp Accommodates a WB-67.

• No Right On Red & Right Only Signal Phased Separately From Crosswalk Signal.

• If There Are Issues With Yielding Compliance At Raised Crossing, Rectangular Rapid Flashing Beacons Or Right-Turn Signal Control Could Be Added For The Southbound Channelized RightTurn.

• Signage: A R1-5 Mod With W1716p Should Be Placed At The Yield Lines At Southbound Channelized Right-Turn.

Where is the bridge?

After much exploration, a bridge crossing was considered too costly and complex an option to pursue further due to the height required for clearance over Haynes Bridge Rd, the resulting length of ramp structure, and potential private property impacts required to meet existing grade.
