Just a reminder that the Northbound I-405 freeway will be closed this Saturday night, August 24 from 11 p.m. to 9 a.m. Sunday to enable the I-405 Sepulveda Pass Improvements contractor to complete removing the steel supports needed to build the new Mulholland Bridge in the Sepulveda Pass.

Metro’s contractor began removing the steel supports two weekends ago.

This is the last freeway closure needed for this activity, referred to by the trades as “falsework removal.”

The project team reports that most of the new bridge deck has been poured at this point.  Next, the contractor is scheduled to close the bridge down at night starting August 26 to work on the bridge’s approach slab.  See construction notice here.

The good news is that Metro anticipates completing the new bridge in late 2013. The bridge known for two Carmageddons will soon be ready for a ribbon-cutting.

Closer view of the steel girders on northbound I-405. The girders are being supported from above the bridge via specially manufactured, threaded “coiled rods” to ensure their safety and stability. The contractor put this novel falsework removal method in place to comply with required freeway closure times and schedules. These schedules are part of the contract to help reduce construction impacts for motorists.

Here’s the updated construction notice info:
