New Configuration Coming for Route 50 / Stone Springs Boulevard 

Many of you have given me feedback on the intersection of Route 50 and Stone Springs Boulevard – in particular, the frequent delays that occur to travel north across the intersection or west onto Route 50. I know sometimes it may seem like nothing happens when you give that kind of feedback, but my staff and I are often working internally with various agencies to examine the issues and see if there are ways to improve them.

This intersection is one of those examples, and I’m ready to share our action plan going forward. The County’s transportation staff and VDOT Traffic Engineering analyzed the intersection configuration and signal timings. As expected, three areas were identified – the two movements I mentioned plus the southbound straight across movement. You may not have noticed, but over the last year signal timings themselves were adjusted in an effort to alleviate delays. Sadly, they did not have much impact.

Since that didn’t work, we needed a new approach. Subject to Board of Supervisors approval on February 18, the County and VDOT have agreed to the following changes:

-The signal will become a split phase for northbound and southbound movements. Adding a phase does result in an increase in wait time for the other movements, but the engineers believe the impact won’t be substantial in concert with the changes below.

– The northbound lanes will be reconfigured. Currently there are 1 left turn lane, 1 through lane, and 2 right turn lanes. It will be changed to 1 dedicated left turn lane, 1 shared straight / left turn lane, 1 shared straight / right turn lane, and 1 dedicated right turn lane.

– The southbound lanes will also be reconfigured. Currently there are 2 left turn lanes, 1 straight lane, and 1 right turn lane. It will be changed to 1 dedicated left turn lane, 1 shared left turn / straight lane, 1 straight lane, and 1 dedicated right turn lane.

Based on analysis done by VDOT, these changes should reduce delays for northbound left turns during the morning commute and, even more significantly, for southbound through traffic during the evening commute. The model predicted some trade-offs in the off-peak direction of travel, but nothing significant.

To make these changes, VDOT will have to conduct signal modifications. They can do this themselves, and the cost will fall between $15,000 and $23,000, which the Board will be asked to allocate next month. I’ll update you in the February newsletter if we hear new timeline information or any other details about the project.
