10. McKinney Lamar Viaduct / Continental Viaduct c.1931
Completed in 1931, the McKinney-Lamar (Continental) Viaduct was one of 4 vehicular bridges created in the early 1930's to alleviate traffic and congestion to and from Oak Cliff. It also provided routes free from worry of flooding from the Trinity River. Before the completion of the 4 viaducts, the Houston viaduct served as the sole secure connection to and from Dallas. The other bridges along with a streetcar viaduct were at Commerce, Cadiz and Corinth. A $6,950,000 bond issue was approved by voters on 3 April 1928, which provided for the construction of the bridges.
The $6,950,000 bond issue was tied to a larger $23,900,000 Ulrickson Plan bond issue, which called for civic improvements over a nine year period and incorporated elements of an earlier plan by George Kessler that would straighten and move the Trinity and construct 25 miles of levees. The catastrophic flood of 1908 had motivated city leaders to make sure such a devastating event never did such damage ever again.
The Cadiz was demolished to make way for I-35.
The preferred build alternative 3C of the modern day Trinity Toll Road adversely impacts this important historical and cultural resource. The above new beautiful deck park cost $8.35 million. If the toll road is built, the area above to approximately the second or third light pole would have to be removed and rebuilt.
According to NTTA's own documents on their website and at a presentation on April 24 at the Kay Bailey Hutchinson Convention Center:
The Continental Avenue Viaduct was constructed in 1931 and is eligible for the National Register of Historic Places. (eligible under Criteria A, Community Development, and C, Engineering).
The No-Build Alternative does not adversly impact any Dallas historical resources.
