New Hampshire Route 106


New Hampshire Route 106 is a secondary north–south highway in Merrimack and Belknap counties in central New Hampshire. It connects the town of Pembroke with Meredith in the Lakes Region.
The first green LED traffic light in the nation was installed at the junction of NH 106 and Loudon Road on May 17, 1996.
The southern terminus of NH 106 is at U.S. Route 3 in Pembroke just south of the Concord city line. The northern terminus is also at US 3, south of Meredith.

Speedway access

is located on NH 106 in Loudon, approximately north of the interchange with I-393. Because the highway was not designed to handle the heavy traffic flows during the busiest NASCAR events at the speedway, traffic flow on NH 106 is shifted between I-393 and the speedway to ease congestion. Full-width breakdown lanes allow for four total lanes of travel during these events.
Leading up to the events, the road is converted so that there are three northbound travel lanes. All southbound traffic uses the southbound breakdown lane.
Immediately following the events, the road is converted to southbound-only traffic. Northbound traffic is detoured onto I-93 northbound to exit 20 and must use NH 140 from Belmont to reach NH 106.
