Project  63-703

Relocation of Interstate 91 (I-91) Northbound Exit 29 and Widening of I-91 Northbound and Routes 5/15 Northbound to I-84 Eastbound: 
This portion of the Project (State Project No. 63-703) will address safety concerns associated with congestion and operational failures in Hartford and East Hartford at Exit 29 on I-91 northbound, which connects to Routes 5/15 North, Route 2, and I-84 East.

Existing Conditions – There is congestion on I-91 northbound; queueing in the right lane of I-91 northbound has been observed to extend as far as approximately 1.4 miles due to the following conditions:
  • I-91 northbound Exit 29 off-ramp has a steep vertical grade with a significant volume of heavy vehicles, and traffic volumes are near capacity.
  • I-91 northbound mainline is also at, or near, capacity; the lane-drop from four, to three lanes, at Exit 27 contributes to the congestion.
  • Traffic on the northbound portion of the Charter Oak Bridge experiences heavy weaving of vehicles entering from the I-91 off-ramp to Route 15/I-84 with vehicles from Route 15 traveling to Route 2 and Route 5. 
  • Relocate I-91 northbound Exit 29
    • Provide two lanes
    • Construct new exit ramp, exiting I-91 northbound from the left lane, and entering the Charter Oak Bridge from the left lane (5 spans, 880’ long)
  • Widen I-91 northbound
    • Extend four-lane section from Exit 27 to Exit 29
    • Widen Route 15 northbound 
    • Provide four lanes from Charter Oak Bridge to the Silver Lane underpass
 Suggested Sequence of Construction
  • Stage 1 – Lower roadways under bridges
  • Stage 2 – Widen I-91 northbound
  • Stage 3 – Construct new Exit 29 ramp
  • Stage 4 – Remove existing Exit 29 ramp, widen 5 spans and restripe the Charter Oak Bridge
