One of the busiest crossroads in the Lehigh Valley will undergo a major reconstruction project starting Monday, May 21.
Motorists should use extra caution at the interchange of Route 22 and Route 145/MacArthur Road in Whitehall Township, Lehigh County.
This first of five phases involves the construction of a temporary
pedestrian bridge over 22, adjacent to the 145/MacArthur Road overpass. The
temporary bridge will accommodate pedestrian traffic during the reconstruction
of the interchange.
This initial work will require about one week of nighttime lane
restrictions on 22 between 15th Street and Fullerton Avenue. Motorists
should anticipate weeknight lane restrictions on US 22 east or west between
10 p.m. and 6 a.m. next week (May 21 through May 25).
This US 22/PA 145 Interchange Project involves:
- Reconstruction of PA 145/MacArthur Road in the area of the interchange
- Replacing the PA 145/MacArthur Road Bridge over US 22
- Construction of new interchange ramps
The construction of the temporary pedestrian bridge is expected to be
complete this summer when the project enters its second phase.
The second phase will mark the start of the major reconstruction of the interchange.
The interchange is being reconfigured to eliminate the current merging
movements on the US 22 on/off ramps by replacing the cloverleaf interchange
with a diamond interchange.
Other improvements include:
- New traffic signals on PA 145/MacArthur Road at the interchange ramps
- Constructing a wider, taller PA 145/MacArthur Road Bridge over US 22
The project is designed to improve traffic flow for the 87,000 vehicles
travelling US 22 and the 38,000 vehicles travelling PA 145/MacArthur Road
PennDOT created a website for this PA 145/US 22 Interchange Improvement Project. The website contains information on the status of the project, feeds from US 22 traffic cameras near the interchange, and allows for the public to sign up for email updates.
