City of Everett Edgewater Creek Bridge Replacement <br /> WORK ELEMENT 8 -TRAFFIC CONTROL: <br /> This work element is performed by Gibson Traffic Control (GTC)to provide detour and traffic <br /> control plans for the Contractor's use in constructing the proposed bridge,and roadway <br /> improvements under both partial and full closure scenarios. <br /> The consultant will complete traffic analysis showing up to 4 alternative diversion route time <br /> specific travel time difference of full closure plan compared to partial closure and no closure <br /> options using standard synchro analysis of key intersection delay and standard travel speed. The <br /> alternative routes times to be discussed with the City (i.e. weekday AM eastbound westbound <br /> and PM peak(i.e.AM school peak or Boeing AM peak or school PM peak or Boeing PM peak <br /> or standard 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. <br /> Consultant will attend up to a total of four(4) City/WSDOT/Mukilteo/council meeting (s) to <br /> discuss travel routes/detour option impacts <br /> Attend a total of 3 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 with <br /> MUTCD and/or WSDOT/City procedures and standard plans. <br /> Assumptions: <br /> Deliverables: <br /> • Alternative route delay comparisons <br /> • Origin destination results for cut through verses local traffic <br /> • Traffic Control PS&E packages at 30%, 60%, 90%,and 100%design levels. <br /> Page 24 of 42 <br />
