the Wilmington area to Dover. The first section of the DE 1 freeway opened in August 1991 between US 13 in Tybouts Corner and US 40 in Bear. Three months later, the freeway opened north to DE 273 in Christiana. The section of DE 1 between DE 273 and I-95 in Christiana opened in April 1993. As a result, DE 7 was relocated onto the DE 1 freeway for a short distance near the Christiana Mall. The DE 1 freeway was extended from US 13 in Tybouts Corner to St. Georges in December 1995, in which it incorporated a portion of the existing US 13 near Red Lion. US 13 was moved to the new freeway between DE 72 and Tybouts Corner, and DE 7 was extended south along the former alignment of US 13 to end at US 13 and DE 72 in Wrangle Hill. The divided highway portion of DE 7 along Limestone Road was extended north from Milltown Road to DE 72 by 1999. DE 7 from I-95 to north of DE 58 became an extension of the freeway in 1999 with an interchange built at DE 58 in a $25 million construction project. The Delaware Department of Transportation (DelDOT) reconstructed the cloverleaf interchange at I-95 to include flyover ramps between southbound I-95 and southbound DE 1 and northbound DE 1 and northbound I-95, aiming to reduce merging and congestion at the interchange. Construction began in 2011 with work to replace the bridge over DE 1/DE 7 leading to the Christiana Mall in order to allow room for the flyover ramps; this bridge was completed in March 2012. The ramp from southbound I-95 to southbound DE 1 opened on August 27, 2013 and the ramp from northbound DE 1 to northbound I-95 opened on October 17, 2013, with a ribbon-cutting ceremony attended by Governor Jack Markell and DelDOT secretary Shailen Bhatt. A project widening DE 7 to four lanes between Newtown Drive in Bear and DE 273 in Christiana was completed in early 2014. DelDOT is planning to widen DE 1 and part of this involves reconstructing its interchange with DE 273. One version of the plan involves moving DE 7 onto DE 1 from DE 273 northward and disconnecting East Main Street from the DE 273 interchange. New ramps would connect the southbound lanes of DE 1 directly to DE 7 where East Main Street once
