Drivers can expect delays Wednesday on Big Bay Point Road in Barrie.
Enbridge Gas and its sub-contractors will require intermittent lane closures, restrictions and shifts on Nov. 15 between Royal Parkside Drive and Hurst Drive.
This is generally the valley area near the city's water surface treatment plant in the south end.
The traffic disruptions are expected to occur between 8 a.m. and 3 p.m.
The city says these measures are related to alterations of existing underground gas infrastructure.
Timing is also subject to weather conditions.
