During the Town-hosted public input meetings, a variety of concepts, ideas and concerns were raised by residents who live south of Rt. 9 and west of the Town of Hillsboro. The majority of the feedback has related to safety issues, speed limit, truck and increase of traffic on these secondary roads. To address the major concerns, we have:

Worked with VDOT to restrict through trucks,

Reduced the speed limit to 25 MPH,

Accelerated VDOT maintenance,

Worked with law enforcement and LCPS bus driver coordinators to identify necessary warning and hazard signs,

as well as restricted specific traffic on Cider Mill.

 

A number of residents have inquired about the possible revision of the configuration of the local detour route. The suggestion has been made to utilize Cider Mill Road in conjunction with Stony Point Road as two “one-way” legs of the local detour. The proposal would have Cider Mill Rd. (Rt. 751) be the main eastbound local detour for eastbound vehicles exiting from Rt. 9, linking at the intersection of Cider Mill Rd., Stony Point Rd. and Woodgrove Rd. to the remainder of the local detour route.

Under this proposal, Stony Point Rd. (Rt. 719), from the intersection of Cider Mill Rd. and Woodgrove Rd., would be one-way northbound to its intersection with Route 9, with the intent for this leg to be the main route for detoured westbound Route 9 traffic, beginning at Route 9 and Rt. 690 intersection, to reach Route 9 west of Hillsboro.

In response to these queries regarding the project local detour route, the Town of Hillsboro asked for an evaluation of the proposal from traffic engineers at our consulting engineer Volkert.

A summary of their analysis follows:

  • The safety of the detour point intersections has been considered by VDOT traffic engineers with the conclusion that the intersections of Rt. 9/690 and Rt. 9/719—with functional roundabouts in place prior to detour activation—is the safest for the bi-directional flow of detour traffic. The newly suggested detour configuration would introduce a hazardous detour entry point for eastbound traffic at Cider Mill Rd., given the lack of a turning lane, limited line of sight and tight turning radius.

  • Forcing all eastbound local detour vehicles to turn right onto Cider Mill Rd. from Rt. 9 would create substantial queues on Rt. 9 eastbound. As the intersection is less than one mile from the Harpers Ferry Road/Rt. 9 signalized intersection, there is a high probability of an increase in rear-end accidents at the intersections, and west of the intersections.

  • Eastbound travel on the local detour originating on Stony Point Road or any point on Rt. 9 between Hillsboro Rd. and Cider Mill Rd. would require motorists to travel westbound on Rt. 9 to take a left turn at the Rt. 9/Cider Mill Road intersection, competing with oncoming eastbound detour traffic—at what is today an unsafe intersection and turning point with limited line of sight.

  • Imposition of essentially two detour routes, and the conversion of current two-way traffic roads to one-way traffic adds complexity and creates uncertainty and confusion for the traveling public.

  • Allowing right-hand turns onto Cider Mill Rd. during the daily eastbound through-traffic periods (4 a.m. to 9:30 a.m.) will encourage cut through traffic on Cider Mill Rd. in the likely event of eastbound queues on Rt. 9.

  • Allowing right-hand turns onto Cider Mill Rd. during the daily closure periods (9:30 a.m. to 4 a.m.) will encourage trucks from Rt. 9 to attempt to use the local detour.

  • Disallowing two-way traffic on Cider Mill Rd. and Stony Point Rd. would have significant implications for LCPS bus routes that currently use the two routes, bi-directionally.

  • A complete round trip along this route adds about 3.5 miles for motorists, especially local traffic access. Everyone living on Cider Mill and Stony Point roads would be required to follow this flow of travel and put the additional mileage on their vehicles in daily travel.
