According to Wikipedia, trap streets are not copyrightable:
In Nester's Map & Guide Corp. v. Hagstrom Map Co., 796 F.Supp. 729, E.D.N.Y., 1992, a United States federal court found that copyright traps are not themselves protectable by copyright. There, the court stated: "[t]o treat 'false' facts interspersed among actual facts and represented as actual facts as fiction would mean that no one could ever reproduce or copy actual facts without risk of reproducing a false fact and thereby violating a copyright . . . . If such were the law, information could never be reproduced or widely disseminated." (Id. at 733)
