An 11-foot diameter limestone core has become a ‘geotechnical monument’ of sorts according to the good folks at Dan Brown and Associates. DBA was the geotechnical designer for a new bridge carrying I-70 over the Mississippi River in St. Louis. The core is located on the west bank (St. Louis side) near the new bridge.

Comments Off on Colorado’s I-70 Could Have Boston’s Big Dig Beat
The planning board for transportation improvements along the I-70 corridor in the Denver area of Colorado is pondering some improvements that, if implemented, could rival Boston’s "Big Dig" for cost. A high-speed train is being considered which alone could run $12 billion.
"A high-speed train is really the long-term solution, and . . . part of America’s long-term future is getting people out of single-occupancy vehicles," said Penny, Frisco town manager and head of the I-70 Coalition. He added that an I-70 project could outstrip Boston’s $14.8 billion "Big Dig."
