The arrival of NASCAR racing in Loudon on Sunday means changes to traffic patterns in the area.

More than 42,000 spectators and 15,000 vehicles are expected to attend the NASCAR Cup Series Race at the New Hampshire Motor Speedway.  The race starts at 2:30 p.m., with the period of maximum traffic congestion expected to occur in the late afternoon and early evening hours. 

Traffic changes on Sunday, race day, are similar to recent years.

The I-93 corridor:

From approximately 3:15 to 9 p.m. the following ramps will be closed along the Interstate 93 corridor, with drivers directed to other roads:  The I‑393 eastbound off-ramp to I‑93 south, 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 be closed. 

 NH 106 Corridor 

On Sunday morning, race day, NH 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 NH Route 106 will be prohibited at several intersections. 

Between 3 p.m. and approximately 8:30 p.m., NH Route 106 northbound traffic will be detoured easterly on NH Route 129 to NH Route 107.  NH Route 106 will be configured with multiple southbound lanes.  NH 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 travel on NH Route 106 to the intersection with Beck Road where traffic will merge to three lanes.  The three southbound lanes will continue to just north of the NH Route 129 intersection and merge into two lanes.  From there, two lanes southbound will be provided on NH Route 106 south to I‑393 in Concord.  A second northbound lane will be added from the NHMS South Gate to just south of the NHMS North Gate.
