A highway expansion and transit project for the southern I-25 corridor, dubbed T-REX (Transportation Expansion Project), was completed on November 17, 2006.[149] The project installed wider and additional highway lanes, and improved highway access and drainage. The project also includes a light rail line that traverses from downtown to the south end of the metro area at Lincoln Avenue.[150] The project spanned almost 19 miles (31 km) along the highway with an additional line traveling parallel to part of I-225, stopping just short of Parker Road.
Las taquillas de la Torre Eiffel abren al mismo tiempo que el monumento y, por eso, no es posible comprar la entrada antes de su apertura. Por este motivo, le recomendamos comprar su entrada por Internet para evitar colas en la taquilla. Esto le permitirá comprar una entrada con una reserva de fecha y hora de visita; si elige la primera hora de la mañana, podrá figurar entre los primeros visitantes del día en acceder al ascensor y así evitar las colas en la taquilla.
