Old US 13(S)/DE 1(N-S) and US 13(N-S)/Old DE 1(N-S) Duplex

United States Route 13 and Delaware Route 1 used to join for 9 miles from Odessa to Smyrna in New Castle County. In May 2003, the Odessa-Smyrna segment of the DE 1 tollway was completed and opened. The northern two miles of US 13/DE 1, which used the DE 1 freeway, became DE 1 only as US 13 was relocated back to its non-freeway alignment. At the same time, the rest of the US 13/DE 1 multiplex was eliminated because DE 1 was moved to the newly completed freeway.

On the US 13 south/DE 299 overpass just west of Odessa. US 13 south leaves its traditional alignment through Odessa and follows DE 299 to DE 1. Here US 13 turns left onto the southern part of the northern segment DE 1, while DE 299 continues ahead toward US 301 and DE 15.

Another view of the northern split, this time from DE 299 east. US 13 north does not reach this interchange because it remains on its routing through Odessa.

Reassurance shields southbound on DE 1. A small US 13 shield is added as a temporary afterthought. In May 2003, US 13 south was placed back on its paralleling alignment.

US 13 south/DE 1 passes over another version of US 13 south as the freeway comes to a temporary end.

Next, traffic is taken off the freeway and back to the parelleling divided highway that is now US 13 alone. This spot marks the northern part of the final DE 1 section, which at this time, was almost complete.

Timothy Reichard 3/22/03

The southbound companion to US 13 north on the divided highway is still signed as US 13 even though US 13 south followed the freeway. This quasi-US 13 south is put on an access road on the other side of the DE 1 freeway.

Timothy Reichard 3/22/03

The quasi-US 13 south follows this access road, now with under-construction DE 1 on the left.

Timothy Reichard 3/22/03

The access road crosses back under DE 1.

Timothy Reichard 3/22/03

The access road leads back to US 13/DE 1.

Timothy Reichard 3/22/03

Almost ten miles south of Odessa, the next segment of DE 1 began, and so US 13 and DE 1 split. During the late stages of construction of the intermediate segment of DE 1, US 13 was briefly put back onto the DE 1 freeway, and so the right curve for US 13 is greened-out on this sign.

Close to the southern split, two overhead signs show the upcoming split. The straigh-ahead arrow on the right sign is pasted on top of a exit-right arrow.

US 13 merges onto the freeway, just to immediately exit back onto its divided highway.

Now northbound on US 13 near Smyrna. The new DE 1 overpasses are visible ahead.

Timothy Reichard 3/22/03

DE 1 merges from the freeway onto US 13.

Timothy Reichard 3/22/03

More reassurance shields northbound.

Timothy Reichard 3/22/03

Near Odessa, DE 1 can return to its freeway bypass of the town. Unlike US 13 south, which follows the freeway for two miles near the town, US 13 north stays on the divided highway and leads straight into town.

Timothy Reichard 3/22/03

DE 1 crosses over the old US 13 southbound lanes to merge onto the paralleling freeway. This traffic pattern is reason for the US 13 south routing on the freeway and access road. US 13 north leads to Odessa.
