Crews battle brutal cold to reopen Portsmouth bridge

PORTSMOUTH - Despite temperatures below freezing and brisk winds, maintenance crews were busy trying to repair the Sarah Mildred Long Bridge on Thursday.

The lift span of the "middle" bridge connecting Portsmouth and Kittery, Maine became stuck about a foot above the roadway during a routine lift on Wednesday afternoon closing the bridge to both vehicular and marine traffic.

The span went askew when being lowered and actually jumped its guides, causing structural steel damage in the process, according to officials with the New Hampshire Department of Transportation.

On Thursday afternoon, Steve Johnson, assistant administrator for bridge maintenance with NH DOT, said he did not yet have a timeline on when the bridge would be fixed, but said it was unlikely to be open by Friday morning.

He said the damaged guides have to removed to get the span back in its grid before the guides are repaired and additional safety steel is fabricated and put in place to prevent the problem from happening again.

Steel fabrication was underway at the NH DOT's Franklin yard on Thursday, Johnson said.

"It's not an easy job, even in good weather," Johnson said.

He said crews had been out since 7 a.m. and were working as quickly as they can to get the bridge repaired with an Irving oil tanker waiting upstream to get out and large boats expected to arrive this weekend.

Bill Boynton, spokesman with NH DOT said the preferred position for the bridge's lift span would be up to allow marine shipping traffic to get through, but right now, the span is stuck where it is.

With the Memorial Bridge connecting the two states via Route One out of commission until July, vehicular traffic has all been re-routed over the I-95 high-rise bridge for the time being.

The Sarah Mildred Long bridge is the state's number one "red-listed" bridge, meaning it is the bridge most in need of repair.
