Those wanting to drive up to the summit at East Rock Park will need to do so before Thursday.
The access road is set to close for the season that day with snow in the forecast.
Visitors to East Rock will still be able to hike to the top of the park by foot.
Officials stated that the access road is expected to reopen next April as weather conditions permit.
The road stayed open later than usual this year to accommodate a longer leaf-peeping season.
