22 <br /> <br />• Updated environmental document will be available for public review and input at the end 1 <br />of October. 2 <br />• Proposed project refinements and enhancements include changes to: 3 <br />o Blackwell/Mangum station, Gateway Station, Erwin Road, Pettigrew Street, MLK 4 <br />Jr. Station park-and-ride lot, Shannon Road, Patterson Place Station, and Alston 5 <br />Avenue. 6 <br /> 7 <br />John Tallmadge said there are some other relevant issues: changing the width and the 8 <br />length of the platforms from a 3-car to a 3-car platform as a value engineering measure; and 9 <br />use of a single track bridge crossing over New Hope Creek, lessening the impacts and costs. 10 <br />He said neither of these changes will negatively impact service. He resumed the presentation: 11 <br /> 12 <br />Erwin Road 13 <br />Design considerations: 14 <br />• Avoid hospital utility relocation. 15 <br />• Maintain access to medical centers. 16 <br />• Minimize property impacts. 17 <br />Proposed solution: 18 <br />• Realign and elevate a portion of the Erwin Road tracks. 19 <br />• Elevate the LaSalle Street station and Duke/Durham VA Medical Center station. 20 <br /> 21 <br />Pettigrew Street 22 <br />Design considerations: 23 <br />• Avoid possibility of large vehicles getting stuck with the required change from sloping 24 <br />roadways to flat tracks at railroad crossings in downtown Durham. 25 <br />Proposed solution: 26 <br />• Raise the elevation of Pettigrew Street approximately 7 feet at its intersection with 27 <br />Mangum Street. Mangum Street would transition back to its existing elevation south of 28 <br />Vivian Street. 29 <br /> 30 <br />Blackwell Street 31 <br />Design considerations: 32 <br />• Enhance safety and pedestrian access for a downtown crossing in great need of 33 <br />improvement. 34 <br />• Avoid impact to historical landmark. 35 <br />Proposed solution: 36 <br />• Close the existing Blackwell Street railroad crossing to vehicle traff ic. 37 <br />• Work closely with the community to evaluate an alternative connection near Blackwell 38 <br />Street, most likely in the form of a bicycle and pedestrian bridge. 39 <br /> 40 <br />Dillard Street 41 <br />Design considerations: 42 <br />• Acknowledge existing traffic patterns. 43 <br />• Mitigate ways current railroad operations pose challenges to vehicle, pedestrian and 44 <br />light-rail traffic. 45 <br /> 46 <br />Proposed solution: 47 <br />• Convert Dillard Street to one-way southbound between Ramseur and Pettigrew streets 48 <br />to improve light rail and existing freight rail operations. 49
