St. Louis

St. Louis Inset from the 1961 Missouri Official Highway Map.

The Gateway Arch was completed in 1965 as the signature piece of the Jefferson National Expansion Memorial along the Mississippi River. Standing at 630 feet tall, the Gateway to the West is the tallest man made monument in the United States. A tram provides tourists access with an observation deck at the apex of the arch. 06/01/11

Eads Bridge

The Eads Bridge was the first span built across the Mississippi River. Designed by James Buchanan Eads in 1867, the ribbed steel arch bridge was constructed between 1868 and 1874.² The double decked crossing was dedicated on July 4. The top deck included pedestrian walkways and a vehicular roadway, including two street car lines, while the lower deck supported two railroad tracks. Trolley tracks were removed from the upper deck in 1942 and the entire deck replaced in 1947.¹ Train service (AMTRAK) halted across the Eads Bridge in 1974, leading to the removal of the tracks from the lower deck.²

The Eads Bridge closed on December 15, 1991 for the construction of the MetroLink station on the Missouri side of the span. It was planned to reopen around July 1, 1992 after completion of the lower rail deck³ but structural concerns over the safety of the bridge kept the bridge closed to vehicles. The top deck was removed for the addition of MetroLink on the lower deck, which began service in July 31, 1993. A new deck was later added, leading to the bridge reopening to pedestrians and bicyclists on July 4, 2003 and to vehicular traffic on July 7.⁴
