An early-morning crash involving five cars Wednesday caused traffic delays along the main road leading to the San Diego International Airport.

The collision happened just before 5:40 a.m. at North Harbor Drive and Winship Lane. Its aftermath temporarily shut down two lanes on North Harbor Drive.

About 20 minutes later, the San Diego Airport tweeted that the accident was impacting traffic near the entrance to Terminal 1. The Airport Authority suggested travelers heading to the airport give themselves extra time due to the delays.
