Phasing in the new boulevard

Support is growing for City to River's vision for removing the downtown lanes of I-70 between the riverfront and downtown after the opening of the new I-70 bridge.

The challenge of solving logistics is high on the priority list of planning this project. How would you like to see construction of the new boulevard phased? Here are some ideas.

Opening of the new I-70 bridge is scheduled for 2014. With the slow economy, it's possible the project will be completed ahead of schedule.

Starting in the Fall of 2010, planning and engineering for the new boulevard and highway removal begins. City to River works to engage interested parties in keeping project on track.

Upon opening of the new bridge, close the former I-70 downtown elevated lanes between the new I-70 bridge and the Poplar Street Bridge. I-55 traffic is directed onto Memorial Drive or across Poplar Street Bridge. I-70 traffic is rerouted across the new bridge or onto city surface streets.

Demolish the old elevated lanes and grind the rubble for clean fill. Recycle structural steel from the elevated lanes. According to engineered plans, begin process of filling in the depressed lanes. Bring the void of the depressed lanes up to grade. During this time, Memorial Drive remains open.

Once depressed lanes are brought to grade, demolish the transition between the old walls of the trench and Memorial Drive. According to engineered plans, compact the entire area creating the roadbed for construction of the lanes of the new Memorial Drive, on-street parking, and landscape medians and other amenities.

Schedule all work to be completed within one year of completion of opening of the new I-70 bridge. With this schedule, the new boulevard is open nearly on the same schedule as the new improvements to the Arch grounds.

Can the Lou ever get its mojo back?

"The chances of St. Louis getting a hub if the landing fees were a tenth of what they are now, or double what they are is just the same -- zero," Boyd said.

The damage has already been done. Highways throughout the region divide neighborhoods and makes living here substandard. Selected improvements to government property can help but simply updating a tourist destination won't change what needs fixing.
