I-35 and Main Street Interchange Project

On April 16,
2014 at 12:00 a.m. (midnight), the contractor opened to traffic the Main Street and Interstate 35 Interchange.   The on-ramps and off-ramps between I-35 and Main Street were opened to traffic as well as all of the traffic lanes on Main Street.  In addition, all new and existing lanes of traffic on I-35 were opened to traffic.  On Thursday, April 17, the contractor completed the final paving improvements on Main Street between Ed Noble Parkway west to 34th Avenue SW. 

Following this week, the contractor will continue working on the final elements of the project including painting of the bridge, abutment and sounds walls; landscaping and sidewalks. 

Construction on the I-35/Main
Street Interchange Project began on Monday, January 7, 2013. This is a $30 million construction project awarded to a joint venture of Allen Contracting and Manhattan Road and Bridge of Oklahoma City.    The construction contract allows the contractor to earn early completion incentive pay at $15,000 a day with a maximum of 100 days.  The Oklahoma Department of Transportation (ODOT) is administering the construction of this project.

 The project involves the following construction elements:

the existing Main Street Bridge and interchange with a Single Point Urban Interchange (SPUI).  The SPUI will include longer on and off ramps at I-35 and a wider Main Street Bridge. The SPUI will allow large volumes of traffic to negotiate the area using a single set of traffic lights mounted at the center of the bridge.  This is the second SPUI interchange in the State of Oklahoma; the first SPUI was constructed at I-40 and Morgan Road in 2012.
