ST. LOUIS (KPLR) - The renovation of the Arch grounds hits a significant milestone this week.

On Friday, crews will reopen Leonor K. Sullivan Boulevard from the Grand Staircase south to Chouteau, but will also close it from the staircase north to Biddle Street.

Among the improvements that have been made to the nearly completed section is raising the roadway 2.5 feet to cut down on flooding.

There is also now a fluted concrete wall much higher and nicer than the old one.

On top of the wall, there are concrete pylons that will serve as bases for new street lighting.

There is also a new ten foot wide lane for cyclists.

The most significant change is the idea that started it all, the "park over the highway," which already is over the highway though not a park yet.

Landscaping begins in the fall.

"The next biggest piece of the project that is really exciting is the museum," said CityArchRiver Foundation Executive Director Maggie Hales.

"Bids for construction of the museum are due this Friday. It will be under construction by mid-March," Hales said.

The museum is expected to open in 2017.
