Northbound I-65 access to westbound I-70 will be detoured west on I-465 in southern Marion County during the ramp closure.
An analysis by INDOT traffic engineers predicted that maintaining a single lane of ramp traffic through the work zone would result in a far longer construction timeframe and miles-long traffic backups, which would block traffic on I-65 and at nearby interchanges. Closing the ramp through the work zone will expedite completion of the project while providing a safer environment for workers and motorists.
I-65 and I-70 traffic should also expect overnight and weekend single-lane closures as crews work on the bridges above.
The bridge construction will affect some Indianapolis city streets. Morris Street and Prospect Street will be closed to vehicular traffic where it crosses I-65 but access to the ramps entering and exiting the interstate will remain open on each side of the bridge. Pedestrian access under the bridge is expected to remain open most of the time, with some short-term restrictions during demolition.
Additional traffic volumes should be expected on nearby ramps and local city streets – especially during the peak morning commute hours. Many downtown commuters who would normally exit at Meridian or West streets may temporarily exit at Raymond, Morris or Washington streets.
INDOT is working to balance the interests of adjacent neighborhoods and the thousands of motorists that use I-65 and I-70 each day. The initial phase of removing the existing concrete deck is expected to generate the most noise and dust.
Motorists, residents and businesses are encouraged to learn more about the closure and how it might affect them by visiting www.Southsplit.in.gov and signing up for email updates. Begin planning now. You may have to take a different route to work or inform employees about how they will be affected. Contact suppliers, delivery trucks, clients and customers to minimize any impacts to business. Plan to allow more travel time once construction begins, and be more courteous to fellow drivers.
INDOT is eager to reach out to community groups, residents and businesses in as many ways as possible. News media, social media and regular email updates will be used to keep the public informed every step of the way and throughout the project. Social media users should “like” the Indiana Department of Transportation: East Central on Facebook and follow @INDOT_ECentral on Twitter for updates using #SouthSplit.
The current South Split project is the second recent one involving the I-65/I-70 interchange area in downtown Indianapolis.
The first I-65/I-70 South Split Project on the east side of downtown Indianapolis was essentially completed in October 2013. The East Street bridge over I-70 opened to four lanes of traffic in October 2014 after a six-month deck reconstruction project that increased the clearance over the interstate by more than a foot.
Raising the East Street Bridge was the final component of a project to increase clearances on eight bridges over I-65/I-70 in downtown Indianapolis. In Fall 2013, the pavement beneath seven South Split bridges was reconstructed and lowered to allow for increased bridge clearances and reduced potential for collisions from unpermitted and off-route trucks with oversize and unsecure loads. Since the lowered pavement was opened to traffic in October 2013, to date there have been no such bridge strikes.
