A brush fire in the median of the Maine Turnpike in Scarborough in the area of exit 42 was slowing traffic Friday afternoon, one of multiple delays reported throughout the day by the Maine Turnpike Authority.

All travel alerts were lifted by 5:30 p.m.

The authority reported the brush fire around 4:20 p.m. One southbound lane was closed, but both lanes were reported open again by 4:45 p.m., though traffic was slow.

Additionally, heavy traffic around 4 p.m. between Kittery and the New Hampshire state line was slowing travel.

Earlier, a tractor-trailer fire in the southbound stretch of the Maine Turnpike between Ogunquit and York caused traffic delays that began just before noon and continued into mid-afternoon.

Turnpike officials said the box trailer of a truck caught fire shortly before noon. Emergency officials responded and the fire was contained by about 12:30 p.m. However, one lane of the two-lane section of highway had to be closed to remove the vehicle, which caused significant delays.

In the afternoon, an alert was issued in the Gray area, where heavy traffic was reported to be causing delays.
