Line Painting and Seal Coating Operations Continue this Week in District 11

Pittsburgh, PA – PennDOT District 11 is advising motorists that line painting and seal coating operations on various roadways in Beaver, Lawrence and Allegheny counties will occur Monday through Friday, September 21-25, weather permitting.

Work to repaint lines and seal coat the road will occur from 7 a.m. to 4:30 p.m. Monday through Friday in the following locations:

Allegheny County

  • I-79 in various municipalities between PA Route 60 and the Pennsylvania Turnpike Southern Beltway

  • I-376 (Parkway West) from I-79 interchange to the Fort Pitt Tunnel

  • Route 51 in various municipalities

  • Route 50 in various municipalities

  • Route 121/Route 3052 (Greentree Road) in various municipalities

PennDOT advises motorists to exercise caution and patience and suggests allowing at least 250 feet (13 car lengths) behind line painting equipment to avoid damage.  Motorists should avoid passing the paint vehicles unless directed by a paint crew member or flag person to do so.  Passing too quickly can cause damage to fresh paint lines and may result in paint on the motorist’s vehicle.  Line painting vehicles normally pull over every two and one-half miles or when safety permits.  Recent technological advancements on the mix of formulas have produced fast dry paints that are dry to the touch within 2 to 3 minutes.  It is crucial to stay off these lines during the curing period.

Motorists who accidentally get paint on their vehicles should immediately wash the paint off with a high-pressure water stream and detergent.  Dried paint can be removed with de-natured alcohol and a soft cloth.  Generally, PennDOT is not responsible for paint on vehicles.

Roadway line painting is an important part of PennDOT’s highway safety initiatives. Paint lines provide direction, delineation, and guidance to motorists.

Glass beads applied on top of wet paint during the painting process provide retro reflectivity.  These small, spherical beads reflect light during dark hours and periods of low visibility.  As the glass beads become worn or wet, the reflectivity becomes greatly diminished resulting in reduced visibility during dark and wet hours.

Lines need repainting each year because of normal wear, tear, and weather. Winter maintenance activities such as plowing, spreading anti-skid materials, and studded tires are very abrasive to paint lines and can cause fading.  Normal weathering caused by snow, rain, and ice also contribute to line reflectivity reduction.

Motorists should use caution and be aware of changing traffic patterns when driving through the area.
