The expansion of Children’s Healthcare of Atlanta at Scottish Rite in Sandy Springs will require the closure of Meridian Mark Road next to the hospital this weekend as a construction crane is installed.

Also beginning this weekend, the right-hand lane of northbound Meridian Mark between Johnson Ferry Road and the Glenridge Connector will be closed for 12 months as the hospital, at 1001 Johnson Ferry Road NE, adds a fifth story and 57 new beds to the main building along that street.

The city advises motorists to use caution and plan for delays. For information: www.sandyspringsga.gov/roadwork
