Thanks for highlighting this new traffic issue related to construction of the Intercounty Connector. I'll post some more information about it during the week, but here's what I'm saying right now on the Get There blog to describe it:
A new traffic pattern will affect motorists using the Shady Grove Road/Interstate 370 interchange in western Montgomery County. Beginning Saturday afternoon, drivers heading west on Shady Grove Road toward westbound I-370 will make a left at a new traffic signal.
They will merge with the eastbound Shady Grove Road drivers heading for I-370 on a new ramp. Variable message signs are in place to alert motorists to the new traffic pattern. Lane closings on both Shady Grove Road and I-370 will begin about 8 a.m. Saturday through the afternoon until the new traffic pattern is in place.
As an alternate route for motorists on west/southbound Shady Grove Road currently using I-370 to get to I-270, motorists may continue on Shady Grove Road beyond I-370 and turn right onto MD 355 (Frederick Road).
Drivers heading for I-270 south traveling from points north should consider MD Route 118 (Germantown Road), Middlebrook Road or MD Route 124 (Montgomery Village Avenue/Quince Orchard Road) to reach I-270 and avoid Shady Grove Road.
The traffic switch allows crews to continue bridge construction within the I-370/Shady Grove Road interchange.
