CONCORD — Through the cooperative efforts of the New Hampshire Department of Transportation, local officials, New Hampshire State Police and the New Hampshire Motor Speedway, a comprehensive traffic control plan will once again be implemented on Sunday when more than 100,000 spectators and 37,700 vehicles are expected to attend the NASCAR Sprint Cup Race at the Loudon racetrack.
The race starts at 1 p.m., with the period of maximum traffic congestion occurring in the late afternoon and early evening hours.
The traffic control measures planned for the race involving Route 106, Interstate 393 and Interstate 93 include:
On race day morning, Route 106 will be two lanes northbound and one lane southbound from I-393 to the intersection of Shaker Road. There will be three lanes northbound and one lane southbound from there to the NHMS south access road. As traffic builds up in the three northbound lanes, traffic control personnel will extend the three lanes southerly to a point south of the NH Route 129 intersection.
Also, on race day morning, the I-93 northbound Exit 15E off‑ramp will provide two temporary lanes of traffic onto I-393 eastbound. In order to reduce congestion on I-93 and promote safety, the I-93 northbound on‑ramp at Exit 14 (Loudon Road) will be closed from 5 to 11 a.m. The ramp traffic will be detoured to either I-393 Exit 1 via Fort Eddy Road or I-93 Exit 15 via Bridge Street and North Main Street. The I-393 Exit 1 eastbound off ramp to Fort Eddy Road will be closed from 5 to 11 a.m. Ramp traffic will be detoured off I-393 via Stickney Avenue or I-393 Exit 2 (East Side Drive).
Between 2:30 and approximately 9:30 p.m., Route 106 will be closed to northbound traffic from I-393 in Concord to NHMS. During this time, three temporary southbound lanes will be provided on Route 106. For safety reasons, the intersections of the following roads with Route 106 will be closed during the one-way conversion: Hollow Root Road, Mudgett Hill Road, Clough Pond Road, Currier Road, Sheep Rock Road, South Village Road, Wales Bridge Road, and Josiah Bartlett Road.
