Minnesota Congressman Jim Oberstar is proposing a $25 billion program to repair or replace deficient bridges throughout the nation. Standing up river from the site of the 35W bridge collapse, Oberstar outlined a plan he said was aimed at preventing similar tragedies. The 8th District Democrat says increasing the federal gas tax by five cents a gallon over three years would help establish a new trust fund dedicated to bridge projects. Oberstar says his proposal would also improve bridge inspection requirements.
