COSMIX: Lane switch at Ellston bridges

       With crews replacing the outside guardrail, curb and gutter on the old portions of the northbound bridge over Ellston Street, northbound I-25 traffic has been temporarily detoured onto the newly widened portion of the southbound bridge. The traffic shift occurred Oct. 2 and will continue for about three more weeks, according to Bill Badger, a spokesperson for Rockrimmon Constructors, the project contractor.
       The work is part of the first phase of the COSMIX project, scheduled to continue through 2007, which will widen I-25 to three lanes in each direction along 12-plus miles from south of the Bijou Interchange to just south of North Academy Boulevard and upgrade several interchanges and bridges.
       On Ellston Street, lane closures are expected to continue through Oct. 7 to rebuild the hillside under the bridge deck. The two- lane street will remain open, Badger said.
       Ellston Street is north of Fillmore Street, going under the interstate between Chestnut Street to the west and Sinton Road to the east.
       At Garden of the Gods Road... The southbound I-25 off-ramp's inside left turn lane will be closed for the relocation of a traffic signal conduit through Oct. 14, from 7 a.m. to 5 p.m., except on the weekend. Traffic will still be able to exit I-25 at Garden of the Gods and turn left.
       The inside left-turn lane will also be temporarily closed at the northbound on-ramp, starting next week and continuing for about seven weeks. The lane closure is in connection with the construction of an improved northbound on-ramp from Garden of the Gods Road, Badger said.
       Noise walls... Starting Monday, installation of the noise walls along I-25 will begin north of Ellston Street in Holland Park. Cranes will lift the walls into place, sliding them into grooves on the concrete columns that have been installed in recent weeks.
