Vernon Viaduct between 2nd Street and 4th Street (BR#54C0066). Back2round: On June 3, 2004, Caltrans issued a report, which resulted from an in-depth "fracture critical" steel inspection on the Mount Vernon Bridge. During the inspection, Caltrans Inspectors determined that various steel members were cracked. These cracks occurred at one span, towards the north end of the bridge in the southbound lanes and toward the south of the bridge in the northbound lanes. Caltrans recommended immediate closure of the entire bridge. The City concurred and completed the closure on June 4, 2004. During the closure, shoring was installed under terms of an emergency contract with Yeager Skanska (now called Skanska USA Civil), On September 21, 2004, the Mayor executed a License Agreement with the BNSF railroad for maintenance of the shoring. Installation of the shoring was completed on October 4, 2004 and the bridge was reopened to traffic, except that large trucks were prohibited from using the bridge. Under terms of the License Agreement, the City has performed annual inspection and maintenance of the shoring, On May 16, 2008, the City was notified of a follow up inspection by Caltrans inspectors that revealed cracks previously not found in two additional girders. The cracks were found in span 6 adjacent to bent 7 near the south end of the bridge. Staff immediately engaged Morris Engineering, Inc, to prepare design plans for shoring the location of the newly discovered cracks. ' A contract was awarded to Skanska on October 6, 2008 to install additional shoring to support the bridge at the location of the newly discovered cracks, That work was completed in November of 2008. In late 2008, it was noted that the License Agreement requires that the City engage a contractor to construct the permanent replacement bridge within 30 months of the execution of the License. BNSF has indicated a willingness to execute a new License Agreement (See attached Exhibit "A") with the City to allow the shoring to remain until December 31, 20 II. Based on the current schedule, construction of the Mt. Vernon Bridge will begin in October of 2010 and be completed by October of2012. 2 c c o CITY OF SAN BERN~INO REQUEST FOR COUNCIL ACTION STAFF REPORT (Continued) Financial ImDact: BNSF has agreed to waive all fees associated with this License Agreement.
