Northbound Loop 360 near Spicewood Springs Road will be reduced to one lane through early September so crews with the Texas Department of Transportation can make emergency repairs to a drainage pipe under the highway.
Heavy rains over the July 4th holiday weekend led to flooding and a partial collapse of the tunnel, causing the pavement to sag. Permanent underground repairs are underway and will require long-term, single-lane closures on northbound Loop 360.
At least one northbound lane will remain open throughout this emergency repair project.
