Factual error: There are several mistakes after McClane steals the 18 wheeler that give away the highway scenes were shot in California instead of Maryland. There are palm trees visible at one point outside the window. There are highway signs that indicate Route 118 and Highway 110, both in California. The scene with the fighter jet is supposed to be on I-695, the Baltimore Beltway, but that road is single-level, not multi-level as the movie shows. A green bridge is visible after part of the highway collapses but there is no bridge that looks anything like that on I-695.
