Exhibit A <br /> SCOPE OF WORK <br /> Diverging Diamond Interchange <br /> Reconstruct the existing diamond interchange at McCaslin Boulevard to provide a Diverging <br /> Diamond Interchange (DDI) according to the following requirements: <br /> 1. Three through lanes in each direction shall be provided through the interchange along <br /> McCaslin Boulevard. <br /> 2. Yield-controlled right and left turn movements shall be provided at the interchange off <br /> ramps, with the exception of the eastbound off ramp to southbound McCaslin Boulevard <br /> right turn movement. This movement shall have three turn lanes and signal control. <br /> 3. Free-flow left and right turn movements shall be provided at the interchange on-ramps. <br /> A southbound right turn lane between Dillon Road and the westbound US 36 on-ramp <br /> shall be included in the DDI. <br /> 4. New traffic signals shall be provided at the crossover intersections. <br /> 5. Islands shall be sized to efficiently channelize traffic, provide pedestrian refuge, safely cross <br /> pedestrians at auto lanes, and allow for urban amenity treatments. <br /> 6. Five foot (5') on-street bike lanes (exclusive of gutter pan) shall be included through the DDI. <br /> 7. Eight foot (8') sidewalks shall be included on both sides of McCaslin Boulevard north and <br /> south of the DDI intersections, and a 12' sidewalk in the center median shall be included across <br /> the bridge. <br /> 8. The 12' sidewalk in the center median shall be separated from traffic lanes by a Type 7 barrier <br /> modified as shown in the McCaslin Interchange Enhancement Concepts. <br /> 9. Two RTD bus stops with RTD compliant pedestrian refuge areas shall be provided at two <br /> locations in the median islands along McCaslin Boulevard between the DDI intersections. These <br /> shall be far side stops on the median side. <br /> 10. RTD park-n-ride accessibility to the west of McCaslin Boulevard shall be enhanced through <br /> use of bus-only ramps accessing US 36 with grade separations from the west side ramps to access <br /> the existing or modified bus stops on the west ramps. <br /> 11. RTD park-n-ride bus staging area and platforms shall be reconstructed and connected to <br /> existing sidewalks, stairs and ramps. Station amenities and landscaping shall be reset or replaced <br /> in kind. <br /> 12. RTD's design standards shall be used for the design of the bus stops along McCaslin <br /> Boulevard, the bus access ways, and the stops, walkways, amenities and platforms at the park-n- <br /> rides. <br /> 13. Design criteria established for the DDI and RTD bus facilities as documented in the Request <br /> For Proposal, herein incorporated by this reference. <br /> Exhibit A, Page 1 of 1 <br />
