US 31 traffic should be alert and anticipate added delays between I-465 and 131st Street as crews implement traffic pattern changes and pavement marking adjustments today, Dec. 15, through Thursday, Dec. 17.

• Northbound and southbound US 31 may be restricted to one lane in each direction while pavement markings are adjusted during daytime/evening hours.
• Northbound US 31 traffic will shift onto new bridges over 106th and 116th streets tomorrow, Dec. 16. Southbound traffic is anticipated to make a similar shift on Thursday, Dec. 17. These traffic shifts will open the freeway to three lanes in each direction and effectively remove the final two traffic signals from US 31 through Carmel.
• After the traffic shift on Dec. 16, motorists wishing to access 106th Street from northbound US 31 must do so via the new exit ramp just north of I-465.
• Drivers headed to I-465 from southbound US 31 will use the new ramp over 106th Street.

Both the eastbound and westbound I-465 exit ramps to northbound US 31 and southbound Meridian Street are anticipated to be widened to two lanes at the end of this week.

All ramps at the I-465/US 31 interchange, including two new free-flowing ramps from I-465 to northbound US 31, are anticipated to be open to traffic and in their final configurations by the end of the year.
