Lehigh and Northampton Counties
The Department of Transportation plans to rehabilitate S. R. 0022, Sections 04M and 027 (US 22) in Lehigh and Northampton Counties involving 8.2 miles of improvements.
S. R. 0022 is a 4-Lane limited access urban arterial that traverses the Lehigh Valley area in an east-west direction. S. R. 0022, Section 04M and Section 027 are located in eastern Lehigh and Western Northampton Counties. The two sections of the highway project are consecutive with Section 04M extending from approximately Fullerton Avenue Interchange (S. R. 8016), Station 819+50 in Lehigh County to approximately 650 feet east of the structure over Hecktown Road (T-440) Station 262+00 in Northampton County.
Within S. R. 0022, Section 04M, the scope of improvements can be divided into three segments: improvements to the Lehigh River Crossing which, including approaches, extends from Station 818+50 to Station 834+62; the mini project, another segment, extends from Station 834+62 (the eastern side of the Lehigh River Crossing) to Station 854+60; and the I-4R Reconstruction and Safety Update project which extends from Station 854+60 in Lehigh County to Station 34+20 in Northampton County (the eastern terminus of the project corridor).
The Lehigh River Crossing consists of four structures, which are actually two pairs of nearly identical bridges (the east and west bound lanes are supported by separate superstructures). The western bridges span the Lehigh River and Conrail tracks west of the river. The eastern bridges span the Lehigh Canal, Conrail tracks west of the Canal, and Dauphin Street.
The mini-project primarily involves replacement of the existing concrete pavement with proposed full depth bituminous pavement. Maintenance of single lane, bi-directional traffic patterns will be necessary to complete the mini project and improvements to the Lehigh River Crossing. The advance completion of these improvements is necessary to allow for maintenance and protection of 4-lane traffic during construction of the I-4R improvements that propose full depth cement concrete pavement reconstruction.
Specific I-4R improvements proposed for S. R. 0022, Section 04M include:
1. Reconstruction of the existing 4-lane concrete roadway pavement.
2. Increase the S. R. 0022 vertical clearance to (16`-6") at each interchange bridge spanning S. R. 0022, except at the Airport Road (S. R. 0987) Interchange where the existing 14 feet 7 1/4 inches underclearance will be maintained. The proposed underclearance beneath the S. R. 0987 (Airport road) overpass will be approximately 15 feet 6 inches based upon the preliminary design grade developed for reconstruction.
3. Improvements to interchange ramp geometry and extensions of speed change lanes to comply with current AASHTO/PennDOT standards.
4. Upgrading of guiderail, roadway drainage, signing, and lighting and removal of obstructions in the clear zone and ramp gore areas.
5. Reconstruction of a modified ramp (Collector Distributor interchange ramp) serving as the S. R. 0022 eastbound exit to S. R. 1009 (Schoenersville Road). The proposed Collector-Distributor ramp will begin at the S. R. 0022 eastbound exit to S. R. 3078 and will merge with the S. R. 0378 northbound exit ramp to S. R. 0022 between S. R. 0378 and S. R. 1009. From the junction of both ramps, the two ramp lanes will follow the present alignment through the S. R. 1009 interchange.
6. Improvements to the Lehigh River Crossing. These improvements include:
a. Replacement of existing armor angle joints with neoprene strip seals.
b. The construction of a trough system to collect roadway drainage and debris from existing finger joints.
Proposed improvements to S. R. 0022, Section 027 include:
1. Replacement and widening of the existing 3 span superstructure with a new steel superstructure supported on the existing structure.
2. Extension of the existing piers and abutments to accommodate the wider superstructure.
This project is not a transportation route or program. However, even if this project is considered to be a transportation route or program, I have determined that no adverse environmental effect is likely to result from this rehabilitation project.
