Rebuilding the interchange has begun, and the first major order of work is to construct the North-to-West (NW) Connector pile shafts. Once the pile shafts are in place the columns can be constructed, and then the bridge deck.
The NW Connector travels from northbound I-215 (from Moreno Valley) to westbound State Route 91 (SR 91) in Riverside. Motorists will notice excavations for pile shafts starting June 28 near the westbound SR 91just west of Spruce Street, and continuing in a south-to-east direction past the interchange to the east side of southbound I-215. Some columns will be placed in the SR 91 and I-215 medians, and inside the existing eastbound-to-northbound loop. Columns will be placed near Down Street, Service Court and Spruce Street on the east side of the I-215.
The NW Connector will be more than a mile long and 46 feet wide, and will measure 72 feet above the roadway at the highest point. It will be supported by 26 rectangular columns which will be placed in 12 foot diameter pile shafts extending down as far as 135 feet in depth. A huge augur will dig the shafts. The NW Connector will be built using 22,498 cubic yards of structural concrete – the equivalent of 2,500 cement trucks and 3,331 tons of bridge rebar (reinforcing steel).
The second connector at the interchange is the South-to-East (SE) Connector. The SE Connector travels from the southbound I-215 (from San Bernardino) to the southbound I- 215 / eastbound State Route 60 (SR 60) towards Moreno Valley.
Shafts will be excavated and columns placed from near West La Cadena and Strong Street, across I-215 inside the existing northwest connector ramp, and near Down and Spruce streets to the SB I-215/EB 60.
The SE Connector will be 3,429 feet long and 46 feet wide, and will measure 65 feet above the roadway at the highest point. It will be supported by 16 rectangular columns that will be placed in 12 foot diameter pile shafts extending down as far as 115 feet in depth. The SE Connector will utilize 14,518 cubic yards of structural concrete – the equivalent of 1,613 cement trucks - and 2,407 tons of bridge rebar.
