Racefans are expected to drive 13,600 vehicles in and out of Loudon on Sunday, July 17, to attend the NASCAR Cup Series Race at the New Hampshire Motor Speedway, and traffic will be affected.

The race starts at 3 p.m., with maximum traffic congestion expected to occur in the late afternoon and early evening.

From approximately 3:15 to 9 p.m., the Interstate-393 eastbound off-ramp to I-93 south will be closed and so will the I-93 Exit 14 southbound off-ramp to Loudon Road and the I-93 Exit 15E southbound off-ramp to I-393 eastbound.

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

On the morning of Sunday (race day), Route 106 will include two northbound lanes and one southbound lane from just north of I-393 to the intersection with Beck Road.  A third northbound lane will be added from Beck Road northerly to the NHMS South Gate.  Left-turns from Route 106 will be prohibited at the following intersections:  Mudgett Hill Road, Voted Road, and Clough Hill Road.

Between 3 p.m. and approximately 8 p.m., Route 106 will be reversed: configured with multiple southbound lanes and one northbound lane open for travel.  During this time, Route 106 will have two southbound travel lanes from the NHMS North Gate to the NHMS South Gate.  Two additional southbound lanes will be added to receive exiting traffic from the NHMS South Gate.  The four southbound lanes will continue to travel on Route 106 to the intersection with Beck Road where traffic will merge to three lanes.  The three southbound lanes will continue to the intersection with Soucook Lane and merge to two lanes.  From there, two lanes southbound will be provided on NH Route 106 south to I-393 in Concord. 

Access to Route 106 from the following roads will be restricted to right-turns only:  Soucook Lane, Brook Circle, Tote Road, Shaker Road, Beck Road, Mudgett Hill Road, Voted Road, and Clough Hill Road.
