Another question: DelDOT seems quite sure that US 202 ends at 95 north of Wilmington, but I see references to it continuing along 95 down to 141 on the internet. Was it truncated?
Haven’t driven that way just yet but will before months end. Otherwise refs to 202 along 95 are absent from Wilmington proper south.
Sign plans for I-95 south at SR 141 removed US 202 when the interchange was being reconstructed. Similarly the sign plans on SR 141 north at I-95 north only included a shield assembly for U.S. 202:
https://www.aaroads.com/forum/index.php?topic=372.msg2508526#msg2508526So US 202 is still considered to be concurrent with SR 141 along Basin Road, but DelDOT does a very sparse job of signing it. It has never been fully signed. And that being said, growing up in Delaware, no one ever referred to U.S. 202 along Basin Road, its was always just "141".
Per the 1984 application to AASHTO for the relocation of U.S. 202:
Extend U.S. 202 from existing U.S. 202 and I-95 along I-95 to Route 141 and along Route 141 to U.S. 13.
This is to provide a high capacity safe connection between U.S. 13, a major north-south route, and U.S. 202, a major route into Pennsylvania and the Pennsylvania Turnpike. Prior to I-95 opening, U.S. 202 connected to U.S. 13 across City of Wilmington Streets. The Department has received continuing requests for a re-establishment of a connection.
The rationale behind Delaware Department of Transportation's proposal to use Delaware Route 141 link with U.S. Route 13 over I-295 is as follows:
1) The section of I-295, just west of the Farnhurst Interchange is considered a high hazard location. A total of 34 accidents were reported in 1981-82-83.
2) The short weaving distance where I-495 merges with I-295 is undesirable for high traffic volume. Eastbound traffic from I-295 toward the U.S. Route 13 exit at the Farnhurst Interchange must weave to the right hand lane which conflicts with the thru traffic and is potentially hazardous.
3) Westbound traffic from U.S. Route 13 onto I-295 has to use a heavily impacted ramp that features a poor Level of Service. The average annual daily traffic (AADT) at this ramp in 1983 was 18,332—the highest in the State.
4) I-295 is used as a major truck corridor between New York City and those states south of Delaware.
The weaving traffic pattern along Interstate 295 was finally eliminated in 2010 when a barrier was added separating traffic between I-95/495 entrance ramp and the U.S. 13/40 southbound exit ramp.
There is no reason to keep U.S. 202 along the overlaps with I-95 and SR 141, other than perhaps red tape.
Bob told me there has been some discussion for truncating U.S. 202 northward back to Wilmington, and also potentially having it extend south over SR 202 to U.S. 13 Business.
