Caserta drove off the road and into a ditch on Sunny Lane, which leads to the Mahackeno grounds, police said.
Caserta told police she got off the wrong exit on the Merritt Parkway and wanted to turn around, but wound up in the construction site, according to the report.
Once she was found, officers said they smelled a "strong odor" of alcohol on her breath. She also failed field sobriety tests, according to police.
Caserta was charged with operating under the influence of drugs or alcohol and released on $500 bond. She is scheduled to appear May 7 in Norwalk Superior Court.
