Avenue 7 Grade Separation

Avison Construction, a small business and Disadvantaged Business Enterprise (DBE) located in Madera County, is laying fresh asphalt at Avenue 7, just north of the San Joaquin River. A roller truck is also being used to ensure the new asphalt surface is compacted and smoothed.

At the edge of Madera County just north of the San Joaquin River Viaduct, crews continue to haul in embankment/dirt to form the mechanically stabilized earth (MSE) walls of the future overcrossing at the Avenue 7 and Road 33 intersection. Eastbound Avenue 7 when exiting State Route (SR) 99 remains closed at this time. Traffic going eastbound will be detoured to the Avenue 9 exit.

At Avenue 7 and Road 33 in Madera County, concrete girders have been set to begin construction of the upper portion of the bridge known as the superstructure. Deck panels for this structure have been set on both spans. This crossing will straighten out a bend in Avenue 7 while realigning Road 33 and allow traffic to cross over the high-speed rail tracks east of State Route 99.

At Avenue 7 and Road 33 in Madera County, a crane set 10 concrete girders to begin construction of the upper portion of the bridge known as the superstructure. Each girder was 110 feet long and weighed about 105,000 pounds. This crossing will straighten out a bend in Avenue 7 while realigning Road 33 and allowing traffic to cross over the high-speed rail tracks east of State Route 99.

At Avenue 7 and Road 33, the abutment walls are taking shape as crews tie the rebar that will make up the interior of the abutment. The substructure is expected to be completed by the end of the month for this crossing that will straighten out Avenue 7, while realigning Road 33 and cross over the high-speed rail tracks east of State Route 99.

Bent falsework has been erected around the columns in anticipation of the bent cap construction. The bent cap will sit upon the columns and support the girders. To the east and west of the bent, abutment footings have been poured, forms stripped, and the site backfilled. Carpenter and laborer crews have begun to build the abutment wall to the north of the structure. The wall forms will then be placed onto the abutments and reinforcing crews will mobilize to install the rebar.
