The city of Broomfield, Colo., has withdrawn from the planning organization for the $250-million Jefferson Parkway, citing elevated levels of plutonium in soil samples taken from the road’s proposed alignment northwest of Denver.
The city was one of several jurisdictions that have collaborated over the last 12 years to develop what was envisioned as a publicly owned 10-mile toll road that would also provide a link in a long-awaited beltway around Denver.
