Interstate 495 in Delaware


Interstate 495 within Delaware is a 11.47-mile auxiliary of Interstate 95 and bypass of downtown Wilmington.  Interstate 495 opened during 1977 and between 1978-1980 briefly served as mainline Interstate 95 while the South Wilmington Viaduct was being reconstructed.  Interstate 495 in addition to bypassing downtown Wilmington serves as access to the Port of Wilmington.  


Part 1; the history of Interstate 495

During 1948 the Wilmington Transportation Study proposed two limited access corridors to connect from Wilmington to the Pennsylvania State Line.  The first corridor would have followed what is now Interstate 95 (Plan A) whereas the second followed what is now modern Interstate 495 (Plan B) as a bypass of Wilmington.  By 1950 Plan A was selected as a limited access corridor from downtown Wilmington to the Pennsylvania State Line.  

On June 29th, 1956, the Federal Highway Aid Act of 1956 was signed into law on the Federal Level.  The Federal Highway Aid Act of 1956 was the genesis point of the Interstate Highway System and established the corridor of Federal Aid-Interstate #3.  Federal Aid-Interstate #3 would go through the process of design during 1960 and be assigned the designation of Interstate 495 during 1962.  

Construction of Interstate 495 would commence during 1968.  The Christina River Bridge would be completed by 1975 and first completed segment of Interstate 495 between US Route 13 to Interstate 95 in Claymont would open during 1976.  During June 1977 the remainder of Interstate 495 would open to traffic. 

On June 28, 1978, the AASHTO approved realigning Interstate 95 onto Interstate 495.  Existing Interstate 95 through Wilmington was requested to be designated as Interstate 595.  The justification for moving Interstate 95 to Interstate 495 was the higher capacity of the then new freeway bypass which had been completed during 1977.  A secondary justification is noted to be the reconstruction of Interstate 95 through Wilmington.  The designation of existing Interstate 95 through Wilmington as Interstate 595 was deferred by the AASHTO in favor of designating a suggested even numbered three-digit Interstate. 








What had been Interstate 95 through Wilmington was approved to be signed as Interstate 195 and Interstate 395 by the AASHTO on October 27, 1978.  Interstate 395 was to be designated from US Route 202 in Wilmington to what had been the Interstate 495 interchange near the Pennsylvania State Line.  Interstate 195 was to be designated from what was the southern Interstate 495 interchange to Delaware Route 141 in Wilmington.  





Interstate 195 and Interstate 395 through Wilmington were approved by the AASHTO to be renumbered to Interstate 895 on June 26, 1979.  








Interstate 95 was redesignated along the corridor of Interstate 895 by the AASHTO on November 15, 1980.  Likewise, the corridor Interstate 495 was restored to what had been briefly designated as Interstate 95.  The justification for restoring the corridor of Interstate 95 was that the project through Wilmington had been completed. 





During June 2014 the Christina River Bridge on Interstate 495 was closed for emergency repairs after tilting support columns were discovered.  The southbound lanes of Interstate 495 would reopen on July 31st whereas the northbound lanes would reopen on August 23th.  


Part 2; a drive on Interstate 495

South of Wilmington, Interstate 495 splits from northbound Interstate 95 via a right-hand transition.  Traffic headed to Philadelphia and the Port of Wilmington are directed onto Interstate 495. 




Traffic on Interstate 495 northbound is advised the Port of Wilmington is 2 miles away whereas Philadelphia is 30 miles.  Interstate 495 is named the Vietnam Veterans Memorial Highway. 


Interstate 495 northbound Exit 1 accesses US Route 13 Business in Wilmington. 



Interstate 495 northbound Exit 2 accesses Delaware Route 9A and the Port of Wilmington.  



Interstate 495 northbound crosses the Christina River Bridge and accesses 12th Street at Exit 3.  





Northbound Interstate 495 Exit 4 accesses Delaware Route 3 and US Route 13 in Edgemoor.




Interstate 495 northbound follows the shore of the Delaware River to Exit 5/US Route 13 in Claymont.  Interstate 495 terminates at Interstate 95 in Claymont approaching the Pennsylvania State Line.

Former US Route 50 and the Pioneer Route Lincoln Highway on Johnson's Pass Road

Johnson's Pass Road is one of the oldest highway corridors in California.  Johnson's Pass was part of the Lake Tahoe Wagon Road as it was completed during 1856 over the Sierra Nevada.  The pass would later be incorporated into the Pioneer Branch of the Lincoln Highway in 1913 and US Route 50 in 1926.  Johnson's Pass Road would be bypassed by a new alignment of US Route 50 over Echo Summit in 1938.  A replacement of the Meyers Grade east of Johnson's Pass would be opened to traffic in 1947.   Johnson's Pass Road remains accessible to traffic and is still signed by the Lincoln Highway Association.  Pictured as the blog cover is the view from the top of Johnson's Pass Road overlooking modern US Route 50 and Lake Tahoe.   Part 1; the history of Johnson's Pass Much of the history of what become the Lake Tahoe Wagon Road is discussed in the  September 1950 California Highways & Public Works  during its Centennial Edition.  The or...

Abandoned US Route 40 in the Truckee River Canyon

Within the Truckee River Canyon in the Sierra Nevada range numerous abandoned portions of US Route 40 can be found alongside modern Interstate 80.   This segment of highway was opened during 1926 as a bypass of the Dog Valley Grade which carried the early North Lincoln Highway and Victory Highway. The corridor of the Truckee River Canyon State Highway would be assigned as US Route 40 when the US Route System was commissioned during November 1926. During 1958 the segment of Interstate 80 between Boca, California and the Nevada state line was complete. When Interstate 80 opened east of Boca numerous obsolete portions of US Route 40 were abandoned. Some of these abandoned segments have been incorporated into the Tahoe-Pyramid Trail.  Part 1; the history of US Route 40 in the Truckee River Canyon The Truckee River Canyon for centuries has been an established corridor of travel known to native tribes crossing the Sierra Nevada range.  The first documented wagon crossi...

Former US Route 50 and the South Lincoln Highway from Folsom east to Placerville

The corridor of Folsom of Sacramento County east to Placerville of El Dorado County has been a long established corridor of overland travel dating back to the California Gold Rush.  The Folsom-Placerville corridor was once part of the path of the Lake Tahoe Wagon Road which became the first California State Highway and later the South Lincoln Highway.  In time the South Lincoln Highway's surface alignment was inherited by US Route 50.  The Folsom-Placerville corridor also includes the communities of; Clarksville, Shingle Springs and El Dorado. Part 1; the history of the Lake Tahoe Wagon Road, South Lincoln Highway and US Route 50 through Folsom-Placerville Folsom is located on the American River/Lake Natoma of eastern Sacramento County.  That lands now occupied by the City of Folsom were part of Rancho Rio de los Americanos prior to the finding of gold at Sutter's Mill during 1848.  During the California Gold Rush the lands of Rancho Rio de los Americanos were p...
