Questions?

Next Steps in Obtaining a Record of Support?

• Confirm Roundabout Rodeo not needed?

• Additional Accommodation Vehicles/movements?

I-84: Swanson Canyon – Arlington (K20274)

Scope - pavement preservation between MP 125-138.

Construction in 2019

MP 125.50 – 132.00 (6.5 miles)

- 3” grind, 5” inlay/overlay

MP 132.00 – 137.78 (5.8 miles)

- Left (“A”) Lane - 5” grind, 8” inlay/overlay

- Right (“B”) Lane – 3” grind, 5” inlay/overlay

Traffic Analysis – single lane conditions remain below

delay thresholds except during Memorial Day and Labor

Day weekends.

16


Single Lane Closure vs Temporary Crossover

• Separation of work zone and live traffic – Safety

• Estimated Paving Production

• Anticipate a 16-20% cost savings over traditional

traffic control of single lane closures option.

• Estimated $2.1M savings based on programmed

construction funding.

US26: Warm Springs Safety Corridor (K19640)

Scope - Repaving the roadway, culvert replacements,

improve roadside cut, implementing safety and traffic

calming improvements, and constructing a 10ft multi-use

path along US26 as part of the 2017 Warm Springs

Commercial Corridor Safety Plan from US26/Kahneeta

Junction (MP103)to Gumwood Lane near Madras (MP112).

ORS366.215 Impacts MP103 to MP105 – Installation of

raised medians/pedestrian refuge islands proposed at

several locations will impact horizontal clearances.

Existing widths = 32ft to 52ft

Proposing 20ft horizontal clearances(curb to curb/edge of pavement)

Seeking Record of Support

31


Draft Plans with Approximate Median/Island Locations

May be slight adjustments, but will maintain minimum of 20ft

horizontal clearance
