Traffic along US Highway 183 switched again Wednesday as the newly-completed southbound lanes opened near Seward Junction.
As contractors replaced and activated traffic signals, Libery Hill police officers directed traffic through the intersection with SH 29.
Project engineers say when construction is complete on the roadway in three months, the intersection will be similar to the intersection at SH 29 and Ronald Reagan Blvd.
Vehicles traveling south on Hwy 183 will make the switch onto the new lanes just north of Seward Junction. Southbound vehicles remain apart from northbound traffic until they reach the point where the original roadway merged into the detoured lanes that opened in December 2010.
The final phase of the $14.7 million project, which was constructed with Pass Through Funding from the State of Texas to Williamson County, will be the completion of the bridge over the San Gabriel River that will take vehicles southbound.
Paul Bowen, resident representative for HDR Engineering, Inc., said the entire project stretches 4.2 miles. He said northbound traffic will eventually be moved to what is now serving local traffic in front of the American RV center, and some of the existing road will be removed.
“When the entire project is complete, we will have eliminated the possibility of head-on collisions,” said James Klotz of HNTB, the construction engineering firm for the Williamson County Road Bond Program.
