Residents and businesses opposed to Albuquerque's rapid transit project are suing.
Attorneys filed two lawsuits Monday that ask a judge to stop the project, arguing the city violated the National Historic Preservation Act as well as local and federal laws.
Mayor Richard Berry's chief staff member Gilbert Montaño says the city has confidence in the project's legal standing.
Construction is scheduled to start in the summer.
One lawsuit was filed in federal court while the other is in state court. Both name federal and city officials.
