I’ll need a bit more context to calculate the distance accurately. The distance from “Essex” depends on which Essex you mean and where you’re located. Assumptions I can use unless you specify otherwise:

• If you mean Essex, England (ceremonial county in the East of England), I’ll need your current location (city, town, or coordinates) to estimate travel distance or route.
• If you mean Essex, Massachusetts (USA), I’ll use your current city or location to compute the distance.

What I can do once you confirm:

• Provide straight-line (as-the-crow-flies) distance between your location and the center of the chosen Essex.
• Provide driving distance and typical travel time using major routes, once you share your exact starting point.

Please tell me:

• Which Essex (England or Massachusetts)?
• Your starting location (city/town or exact address, if you’re comfortable sharing).
