Construction report from I-895 in Maryland:
1. Patapsco Flats Bridge.
All traffic using the new northbound span, much smoother than the old bridge which had very obvious expansion joints - the southbound span appears to be approaching completion. Looks like the contractor is replacing the Jersey wall on the median north of the bridge. This should be complete pretty soon.
2. Canton Viaduct and related.
The prime, Tutor-Perini, started work after Thanksgiving 2018.
The northbound side of the viaduct and the ramp to Holabird Avenue are nearly entirely demolished, and the the contractor has started to pour the concrete for at least one pier.
All traffic is using one lane each way on the old viaduct in what were the southbound lanes.
Speed camera southbound approaching the work zone has been active of late.
In the tunnel, the northbound tunnel deck had about 3 or 4 inches hydro-demolished, and a new surface has been poured using latex-modified concrete.
A lot of the stonework approaching the south portal on the northbound side was deteriorated, and is being repaired.
There will be full closures of the entire road when the structural steel is hung for the new northbound lanes. The only way to get the steel delivered is to use the southbound lanes, so the entire crossing will be closed on at least a few weekends once the piers for the northbound side have been poured and allowed to cure.
