Staging/Phasing Descriptions

• Stage I: Widen inside shoulder to permanent location
• Stage II, Phase 1: Restripe inside and center lane lines
• Stage II, Phase 2: Close Sunnybrook exit ramp and

Sunrise entrance ramp to restripe outside lane

• Stage II, Phase 3: Widen the outside shoulder to permanent

location

• Stage III: Reconstruct the Sunnybrook exit gore
• Stage IV, Phase 1: Grind and inlay the inside two lanes
• Stage IV, Phase 2: Close Sunnybrook exit ramp, Sunrise

entrance ramp, and OR212 entrance ramp to grind and inlay the outside two lanes, Sunnybrook exit ramp, and Sunrise entrance ramp

Detour Routes

• Stage II, Phase 2 and Stage

IV, Phase 2 will require night closures of entrance and exit ramps

– Stage II will close the Sunnybrook/Sunnyside exit ramp and the Sunrise Expressway entrance ramp – Stage IV will close the same ramps and will also close the OR212 entrance ramp

Stage II, Phase 2 Detour Route

MAC Meeting 5/15/2018 K19721 I-205 NB: MP 13.3 – Sunnybrook Exit 9

Stage IV, Phase 2 Detour Route

MAC Meeting 5/15/2018 K19721 I-205 NB: MP 13.3 – Sunnybrook Exit 10

Traffic Shifts

• Stage I will shift traffic ~5’

east of the existing alignment

• Stage II, Phase 3 will shift

traffic onto the newly constructed (Stage I) inside shoulder

• Stages with traffic shifts will

maintain 3-12’ lanes and 2’ shoulders (2’ shoulders only

• n side where work is
• ccurring to maximize work

zone)

MAC Meeting 5/15/2018 K19721 I-205 NB: MP 13.3 – Sunnybrook Exit 11

Vertical Clearance

• Two new cantilever sign

structures will be installed as part of the project – Both structures will be designed to have 19’ of vertical clearance

MAC Meeting 5/15/2018 K19721 I-205 NB: MP 13.3 – Sunnybrook Exit 12

Vertical Clearance – Continued

• Only the inside lane vertical

clearance under the OR224 structure (structure 09718) will be reduced as part of the project due to the parabolic curve of the soffit

• The clearance will still

maintain the minimum 17’-6”

– This clearance is measured at the edge of the inside shoulder
