Whittier Bridge/I-95 Improvement Project FEIR Chapter 3.0: Mitigation and Commitments Task-specific noise mitigation measures that could attenuate pile driving noise will include: (1) the use of hydraulic ―push piles‖ provided that ground resistance conditions allow their use; (2) preaugering pile holes to loosen the substrata; (3) the use of hard rubber pile cushions; or (4) the use or a collapsible bellows system to enclose the piles as they are being driven into the ground. MassDOT will develop a Construction Noise Control Specification specifically for this project and include it in the contractor‘s bid documents and contract. 3-18
Whittier Bridge/I-95 Improvement Project FEIR Chapter 3.0: Mitigation and Commitments 3.16 MASSDEP DRAFT SECTION 61 FINDING This proposed Section 61 Finding is submitted in support of the EA/DEIR describing the Whittier Bridge/ I-95 Improvement Project related to MassDEP permit actions. Project Name: Whittier Bridge I-95 Improvement Project Project Location: Newburyport, Amesbury and Salisbury Project Proponent: Massachusetts Department of Transportation - Highway Division EOEA Number: 14427 3.16.1 Introduction MassDOT proposes to replace the existing I-95 six-lane John Greenleaf Whittier Bridge/I-95 Improvement Memorial Bridge (Whittier Bridge) over the Merrimack River. The project is located in Newburyport, Amesbury, and Salisbury, Massachusetts. The need to improve I-95 north of Boston has been recognized since the 1960s. Originally constructed between 1951 and 1954, the ―Relocated US 1‖ was built to provide expressway service from Boston and its northern suburbs connecting to the New Hampshire turnpike and the Maine turnpike, both of which were constructed in the late 1940s. The four-lane expressway (two lanes in each direction) was constructed from Danvers to immediately south of the New Hampshire state line in Salisbury. From 1967 to 1969, I-95 was widened to provide six lanes of traffic from Danvers over the Merrimack River north to I-495 in Salisbury, and eight lanes of traffic from I-495 north to the Massachusetts-New Hampshire border. The four Whittier Bridge traffic lanes were reconfigured to three 12-foot travel lanes and two 2-foot shoulders in each direction. The reconstructed I-95 was designed to handle the traffic loads of the newly completed I-495, as well as the then-proposed expansion of the New Hampshire Turnpike (I-95). From 1973 to 1977, I-95 was widened further to provide eight lanes of traffic from south of the Merrimack River south to U.S. Route 1 in Danvers. Since opening to traffic in 1951, the Whittier Bridge has undergone major rehabilitation on two occasions. In 1977, the original reinforced concrete roadway deck was replaced and concrete traffic barriers were installed along the curb lines. In 1991, the original bearings were replaced. Since 2003, MassDOT has been carrying out structural repairs to the bridge on a regular basis. The repairs have been temporary/short-term fixes on an ―as needed‖ basis to maintain the bridge in a safe condition until the bridge can be replaced. These repairs have been driven by the results of bridge inspection and load rating reports provided by engineering consultants hired by MassDOT. The 2003 repairs included installing vertical steel rods to supplement the existing deteriorated wire rope hangers, repairing corroded floorbeams and stringers, and repairing bracing members. Strengthening steel plates are currently being installed to reinforce several heavily corroded floorbeam and stringer ends in response to low load ratings. The gusset plates (typical structural elements of a truss bridge) are load rated in accordance with the February 2009 FHWA Gusset Plate Load Rating Guidance, which was issued following the catastrophic collapse of the I-35W truss bridge in Minneapolis, Minnesota on August 1, 2007. 3-19
