Schedule Overview • Bid open: 11/1/2018 • Stage I: 3/11/2019 – 5/30/2019 • Stage II, Phase 1: 5/30/2019 – 6/4/2019 • Stage II, Phase 2: 6/4/2019 – 6/11/2019 – Only two (2) consecutive nights • Stage II, Phase 3: 6/11/2019 – 9/20/2019 • Stage III: 9/20/2019 – 10/8/2019 • Stage IV, Phase 1: 3/30/2020 – 4/15/2020 • Stage IV, Phase 2: 4/15/2020 – 5/7/2020 • Final Walkthrough: 5/22/2020 MAC Meeting 5/15/2018 K19721 I-205 NB: MP 13.3 – Sunnybrook Exit 6

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 MAC Meeting 5/15/2018 K19721 I-205 NB: MP 13.3 – Sunnybrook Exit 7

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 MAC Meeting 5/15/2018 K19721 I-205 NB: MP 13.3 – Sunnybrook Exit 8

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 on side where work is occurring 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 MAC Meeting 5/15/2018 K19721 I-205 NB: MP 13.3 – Sunnybrook Exit 13
