I-476 Northbound Overnight Lane Closures Scheduled Next Week for Bridge
Beam Replacement in Montgomery County

9/15/2017-KING OF PRUSSIA

Motorists will encounter lane closures on northbound Interstate 476 between
the
U.S 30 (Lancaster Avenue) and Interstate 76 interchanges in Radnor
Township,
Delaware County, and Lower Merion Township and West Conshohocken,
Montgomery
County, on Monday, September 18, through Friday, September 22, from 8:00 PM
to
5:00 AM, for beam replacement on the overpass carrying northbound I-476
over
Route 320 (Montgomery Avenue), the Pennsylvania Department of
Transportation
(PennDOT) announced today.

In addition, short-term lane shifts are scheduled in both directions on
Route
320 (Montgomery Avenue) between Matsonford Road and Spring Mill Road in
Lower
Merion Township on Wednesday, September 20, through Friday, September 22,
from
from 8:00 PM to 5:00 AM, for beam replacement.

Motorists are advised to allow extra time when traveling through the
construction areas because slowdowns will occur. The contractor's schedule
is
dependent on the weather.

The underside of the northbound I-476 bridge over Route 320 (Montgomery
Avenue)
was struck by a large truck on July 22, which resulted in damage to the
concrete fascia beam. Following the incident, the bridge was categorized as

structurally deficient.

As part of the work, crews will remove and replace the damaged pre-stressed

concrete fascia beam and adjacent portion of deck and barrier; install new
bearing pads; replace deck joints at the abutments; and remove and
reinstall
barrier-mounted sound wall. Construction on the bridge is scheduled to be
completed in late November.

Built in 1974, the one-span pre-stressed concrete-I beam bridge is 110 feet

long and 56 feet wide. The structure carries about 61,000 vehicles a day.

The work on the bridge carrying northbound I-476 over Route 320 (Montgomery

Avenue) is part of PennDOT's $6.8 million project to rehabilitate/replace
five
structurally-deficient bridges in Bucks and Montgomery counties, three
structurally-deficient culverts in Bucks County, and to stabilize a stream
embankment at a bridge in Bucks County.

Loftus Construction, Inc. of Cinnaminson, N.J., is the general contractor
on
the project, which is financed with 100 percent state funds through Act 89,

Pennsylvania's transportation plan.

Work on the entire project is scheduled to be completed in late 2018.
