What's in store down road in N.H.

New Hampshire Department of Transportation officials this week will be sharing information about I-93 at public hearings.

First, consultants hired to create traffic projections for the I-93 widening project will discuss their findings at public meetings in Londonderry and Salem.

The updated traffic volume information anticipates conditions along the I-93 corridor from Salem to Manchester, both on the highway itself and on secondary roads, in the years 2020 and 2030.

New Hampshire DOT spokesman Bill Boynton said last week that projections are being updated as part of the I-93 rebuilding project's environmental report required by a court order in response to a suit filed by the Conservation Law Foundation.

The first meeting will be held at 7 p.m. Tuesday in Londonderry Town Hall on Mammoth Road. The second meeting is 7 p.m. Wednesday at Salem High School on Germonty Drive.

More information is available at the project's website. rebuildingi93.com.

On Thursday, Granite State transportation officials will discuss the planned rehabilitation of the Merrill's Marauders Bridge on the Everett Turnpike over the Souhegan River in Merrimack.

Boynton said the 242-foot-long structure, built 55 years ago and named after an elite World War II unit, is on the state's "red list" of bridges that need work.

The state has set aside $7.5 million for the project, which will repair the structure's concrete deck and some of its supporting piers.

Boynton said the work, which will probably require lane closures, is to be put out to bid in July. The meeting is at 7:30 p.m. at Merrimack Town Hall.

Dave Murdoch wonders if the Massachusetts Highway Department is trying to give him a bum steer. "Something's been bothering me for a while: Throughout the city on highways you often see signs that read, 'Best Route to Logan' and point in a particular direction," he wrote in an e-mail.

"They're usually helpful, but I've noticed that when you come down I-95 south from New Hampshire, just as you hit Route 1, the signs indicate that you should continue on 95.

"The most direct route into Boston from that area is on Route 1, especially to Logan, where you can cut through Revere. So why are these signs apparently sending you in the wrong direction, at least 10 or 20 miles out of the way (depending if they send you to 93 south or to the Pike). Is it to alleviate congestion on 1?"

Murdoch must have missed the sign. MassHighway spokesman Adam Hurtubise says the signs do direct motorists to Route 1, but farther south of the New Hampshire line at exit 44, the Lynnfield/Peabody exit.

Nighttime steel work has begun on the Cross Street Bridge over I-93 in Salem. The work will take place nightly from 8 p.m. to 6 a.m. and may slow some late commuters.

The work is expected to last until Thursday (depending on the weather) and will require some lane closures both northbound and southbound.

At some points, lifting and setting the steel beams will require the complete halt of traffic for 15 minutes or so.
