Annandale Transportation Study Alternative 5 Figure 14a 2 5 6 1 3 4 1. Improvements in the westernmost section of Little River Turnpike include provision of an eastbound dual left turn lane at Hummer Road within the existing median; therefore, no additional ROW is required for this improvement . 2. The service drive on the north side is closed at its intersection with Hummer and realigned with Championship Drive which has access to Hummer Drive 1,000’ north of Little River Turnpike. This will substantially improve operations at the Little River Turnpike/Hummer intersections by removing the Service Drive operational impacts. 3. The first south side driveway east of Woodland Road has adequate spacing from Woodlawn intersection but would require U-turn movements for access from east and to west on LRT unless an inter-parcel connection is made to the parcel to the west that has access to the signal at Woodlawn. 4. The first and second driveways east of Medford Road (serving the existing housing complex) has adequate spacing from the Medford intersection but would require U-turn movement for access from east unless the section of the current service drive is left that would connect all drives to Medford Drive. 5. The access points between Woodlawn and Hummer would all be made right-in/right-out (RIRO) due to the median in LRT. All these parcels have alternative access to Hummer Road. 6. A mid-block unsignalized crossover in the median provides direct access to the McDonalds and the apartments on the south side of Little River Turnpike. One vacant parcel on the north side of Little River Turnpike will have right-in/right out access; however, an interparcel agreement may be reached at when this parcel is developed to provide access to either the signal at Woodland or the median crossover.
