Mid-coast will be missing out on the Penobscot Narrows Bridge Observatory for a few weeks.  The observatory is normally opened only seasonally, from May 1st to October 1st.  The delayed opening is due to a risk related to  fire suppression if there is indeed a fire event.

The MaineDOT released a statement last Friday:

The opening of the Penobscot Narrows Bridge Observatory will be delayed for several weeks. The observatory's fire suppression system needs to be fully operational before the Maine Department of Transportation can open the observatory to the public. A valve on that fire suppression system failed, so we have ordered a replacement, but the part needs to be specially constructed for us. We hope to be able to open the observatory by Memorial Day weekend.

The tower sits far above the Penobscot Narrows Bridge, which connects the towns of Prospect and Verona above the Penobscot River.
