St Louis’ CityArchRiver Project Ready to Demolish Bridges to Construct New Park Over Highway

The Missouri Department of Transportation will take a major step forward this weekend on the Park Over the Highway project. At 8:00 p.m. Friday, June 6, MoDOT will close all lanes of I-44 (formerly I-70) downtown between Broadway and the Poplar Street Bridge.

The closure will allow crews to demolish the Market and Chestnut Street Bridges between the Old Courthouse and the Gateway Arch. The bridges will be replaced by the Park Over the Highway. Later this summer the interstate will close again, allowing crews to install structural steel girders across the highway to support the park.

The highway will reopen to traffic by 5:00 a.m. Monday morning, June 8.

You can view the ongoing construction on the Park Over the Highway and the rest of the CityArchRiver project from the web cameras at:


CityArchRiver 2015 will make the Arch easier and safer for everyone to experience by connecting, invigorating and expanding the park’s grounds and museums.

Designed by world-renowned landscape architecture firm Michael Van Valkenburgh Associates, CityArchRiver 2015 connects the Gateway Arch grounds with the East and West riverfronts and the region. Through the creation of new spaces for events and public education, expanded museum space, additional park acreage and bicycle trails, children’s play areas, performance venues and a lively, invigorated riverfront, locals and tourists alike will find new opportunities to learn, linger and enjoy one of the world’s most recognized icons.

CityArchRiver 2015 offers the people and institutions who support the St. Louis region a once-in-a-lifetime opportunity to invigorate the jewel of St. Louis and make the Gateway Arch a destination of choice for the young and the old, those near and far, for generations to come.

The design starts with a new, dramatic Park Over the Highway that will, for the first time, allow visitors to walk from the Old Courthouse to the Arch grounds to the riverfront on one continuous greenway, without a curb or stair step in their way. With your support, the CityArchRiver 2015 project will have a lasting impact on the economic, social, environmental, recreational and educational fabric of the entire bi-state metropolitan region.
