The seasonal opening of the observatory at the top of the Penobscot Narrows Bridge will be delayed until further notice.

The observatory typically is closed each year from November through April.

That is the latest closure to come as a result of the coronavirus pandemic. The Maine Department of Transportation announced the closure in a Thursday morning tweet.

A statement on the department’s website said the observatory could reopen on June 1 “at the earliest.”

For those who still want to experience the scenic views, the Maine secretary of state’s office has a virtual tour of the observatory that allows viewers to take the elevator to the top and look out over a virtual Penobscot River. The virtual tour can be accessed at

The 2,120-foot-long cable-stayed bridge carries U.S. Route 1 over the Penobscot River, connecting Verona Island to Prospect. It replaced the Waldo-Hancock Bridge, built in 1931.

The observatory, which opened in May 2007, is the tallest public bridge observatory in the world, according to the Transportation Department. It is one of four bridge observatories in the world, with the other three located in China, Thailand and Slovakia.
