With 90,000 spectators and 33,000 vehicles expected to attend the ISM Connect 300 Monster Energy NASCAR Cup Series race at Loudon’s New Hampshire Motor Speedway on Sunday, traffic will be rerouted in the area. The race starts at 2 p.m., and traffic congestion is expected to peak in the late afternoon and early evening hours.

According to the state Department of Transportation, traffic control measures planned for the race involve NH Route 106, Interstate-393, and Insterstate-93:

I-93 Corridor

The I-93 Exit 12S southbound on ramp from NH 3A will be closed from approximately 10:30 a.m. to 9:30 pm. Motorists will be directed to use I-93 northbound to reverse direction at Exit 13 (use northbound off ramp and turn left to southbound on ramp). Access to Interstate-89 is available at the NH 3A/I-89 intersection in Bow.

Special measures will be used on I-93 from approximately 11 a.m. to 9:30 p.m. Sunday. Three southbound travel lanes will be provided for 5 miles on I-93 from Exit 15 (I-393) to south of Exit 12. This will be accomplished by using the right shoulder as a third southbound travel lane. As traffic approaches Exit 15 from the north, traffic from I-393 west will be received on the shoulder as a new lane. All southbound I-93 traffic destined for I-89 or Exits 12 and 13 should use the shoulder travel lane after the Exit 15 interchange.

The I-393 eastbound off ramp to I-93 south will be closed from approximately 10:45 a.m. to 9:15 p.m. Motorists attempting to use the ramp will be diverted to Stickney Avenue from which they can access I-93 south at Exit 14.

The I-93 Exit 14 southbound off ramp and the I-93 Exit 15E southbound off ramp to I-393 eastbound will be closed from approximately 10:45 a.m. to 9:15 p.m. Motorists will be directed to use Exit 15W to reach Exit 14 destinations and use Exit 16 to reach I-393 eastbound.

The I-393 Exit 1 westbound on ramp from Fort Eddy Road will be closed from approximately 3 to 9 p.m.

At the I-393 and I-93 interchange, the I-93 northbound off ramp to I-393 west (Exit 15W) will be closed from approximately 3 to 9 p.m.

Special measures on I-393 westbound will also be in effect at Exit 15 to enhance access to I-93 southbound. From approximately 3:15 to 9 p.m., the loop ramp for this movement will provide two lanes of traffic. The two lanes will be merged onto the I-93 southbound shoulder travel lane.

NH 106 Corridor

On race day morning, NH 106 will be two lanes northbound and one lane southbound from I-393 to the intersection of Sheep Rock Road. There will be three lanes northbound and one lane southbound from there to the NHMS south access road.

Between 2:30 p.m. and approximately 9:30 p.m., NH 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 NH 106. For safety reasons, the intersections of the following roads with NH 106 will be closed during the one-way conversion: Josiah Bartlett Road, Wales Bridge Road, South Village Road, Sheep Rock Road, Currier Road, North Village Road, Clough Pond Road, Mudgett Hill Road and Hollow Root Road. During the approximately seven-hour period, NH 106 is limited to one-way southbound traffic. Safety vehicles will be stationed at four locations to respond to emergency calls.

NH 106 in Belmont will again be made one-way northbound between the Concord Street/NH 106 intersection and the intersection of NH 140 and NH 106. This section of roadway will be converted to a temporary two-lane, one-way northbound roadway between approximately 4 and 9:30 p.m. On NH 106, two northbound left turn lanes and one through/right lane will be provided at the NH 140 intersection. Southbound NH 106 traffic will be detoured onto NH 140 west to Concord Street, and then back onto NH 106. North Main Street will be temporarily closed. All other streets in Belmont will continue normal operations.

From approximately 2:30 p.m. to 9:30 p.m., the I-393 Exit 3 eastbound off ramp will be open to southbound NH 106 traffic only, and the northbound 106 travel lane will be closed. The I-393 Exit 3 westbound off ramp will be closed to all traffic.
