Page 32 of 59 <br />City of Everett Merrill & Ring Bridge Replacement <br />WORK ELEMENT 8 - TRAFFIC CONTROL: <br />This work element is performed by Kimley Horn (KH) to provide detour and traffic control plans <br />for the Contractor’s use in constructing the proposed bridge, and roadway improvements under <br />both partial and full closure scenarios. <br />KH will complete traffic analysis showing up to 4 alternative diversion route time specific travel <br />time difference of full closure plan compared to partial closure and no closure options using <br />standard synchro analysis of key intersection delay and standard travel speed. The alternative <br />route times to be discussed with the City (i.e. weekday AM eastbound westbound and PM peak <br />(i.e. AM school peak or Boeing AM peak or school PM peak or Boeing PM peak or standard <br />Computer Peak or off peak) <br />Collect data to identify what percentage of the traffic crossing the bridge during standard <br />computer peak is local traffic destined between Mukilteo Lane and Glenwood Blvd and how <br />much is more regional cut through traffic from SR-525 to Glenwood. Number <br />plate/Bluetooth/Streetlight data may be used for this purpose depending on City input. For this <br />proposal, up to $15,000 in origin destination specialized data collection is assumed. Additionally, <br />data from when the Edgewater Creek Bridge is closed will be utilized to evaluate the alternative <br />route impacts. <br />KH will attend up to a total of four (4) City/WSDOT/Mukilteo/council meeting (s) to discuss <br />travel routes/detour option impacts <br />Attend a total of 8 team meetings to discuss what type and duration of closures are needed for <br />which phase of the bridge reconstruction <br />Attend up to 2 neighborhood meetings to present and discuss closure plans. <br />The exact limits of the traffic control will be determined jointly between the CITY and the <br />CONSULTANT and are dependent on full closure or partial closure. The plans will conform <br />with MUTCD and/or WSDOT/City procedures and standard plans. <br />Assumptions: <br />Deliverables: <br />x Alternative route delay comparisons <br />x Origin destination results for cut through verses local traffic <br />x Traffic Control PS&E packages at 30%, 60%, 90%, and 100% design levels.
