NHDOT says hybrid roundabout project at US‑202/NH‑9 will start this June; low bidder ~ $5.6M
Summary
The New Hampshire Department of Transportation told the Henniker Select Board the US‑202/NH‑9 intersection reconstruction (hybrid roundabout) is expected to begin in June, with Weaver Brothers the low bidder at about $5.6 million and completion currently scheduled for September 25, 2026.
The New Hampshire Department of Transportation updated the Henniker Select Board on a hybrid roundabout and intersection reconstruction at US‑202/New Hampshire 9 and New Hampshire 127, saying construction is likely to begin in June and that Weaver Brothers was the low bidder at roughly $5.6 million.
Michael Moser, representing the NHDOT, said the work will include construction of a hybrid roundabout, reconstruction of approaches on US‑202/NH‑9 at NH‑127 and Old Concord Road, CCTV installation, overhead signs, drainage improvements and a water‑quality best management practice. Moser said the department closed bids March 13, internally awarded to Weaver Brothers and expects administrative approvals in May. He said the contract completion date is scheduled for 2026‑09‑25, with a winter maintenance shutdown that may occur after phase 2 or phase 4 depending on weather and construction progress.
The board pressed the DOT for details about traffic control and commute‑hour impacts. Moser described five construction phases: initial temporary widenings, sequential traffic shifts to newly constructed shoulders, 14‑day temporary closures for turning movements into Old Concord Road during phase 3 and for NH‑127 during phase 4, and use of variable message signs and portable changeable message signs to direct motorists. The DOT will apply a standard 10‑mph work‑zone speed reduction and post advisory 35‑mph signs in phases 2 and 4 to slow traffic.
On cost, Moser said the low bid was roughly $5,600,000 and that only two bidders participated; he contrasted that with earlier estimates near $3.03–$3.5 million and attributed the increase to higher construction prices and fewer bidders. A member of the public separately confirmed bid figures were Weaver Brothers at $5.6 million and Piper RM Inc. at $6.2 million.
The DOT representative said public outreach will begin two to four weeks before major traffic shifts and that the department will issue media blasts and update variable message signs when phases change. Moser advised that final traffic pattern notices will be posted on the DOT project page and recommended following the project page for updates.
The Select Board took no formal vote on the project during the meeting. The DOT presentation ended after board questions.
