Relocation of Interstate-91 (I-91) northbound (NB) Exit 29 and Widening of I-91 NB and Route 5/15 NB
to I-84 eastbound (EB). (State Project No. 63-703):
This portion of the Project will address safety concerns associated with congestion and operational
failures in Hartford and East Hartford at Exit 29 on I-91 NB, which connects to Route 5/15 NB, Route 2,
and I-84 EB.
Resurfacing, Bridge & Safety Improvements on I-91 (State Project No. 159-191):
This portion of the Project includes improvements to extend the service life of the pavement and bridges
(milling/paving & subsurface concrete repairs) between the Elm St. overpass in Wethersfield and the
new Exit 29 off-ramp in Hartford.
The I-91 Charter Oak Bridge Project includes two projects designed to reduce congestion and improve safety in Hartford, East Hartford, and Wethersfield:
Contract Highlights:
Contract Administered by CTDOT District 1

Contract Awarded to O&G /BHD, Joint Venture
Estimated Construction Cost - $213 million
Notice to Proceed – April 1, 2019
Maintenance and Protection of Traffic Goals:
Utilize Four Major Stages of Construction
Maintain all Existing Lanes During Peak Periods
Make use of Off-Peak Lane Closures for Short-
Duration Work (e.g. erection of beams)
Maintain Minimum Vertical Clearances for Bridges
Inform the Public of Construction Closures/
Detours and Impacts

Existing Conditions – There is congestion on I-91 NB; queueing in the right lane of I-91 NB has been observed
to extend as far as approximately 1.4 miles due to the following conditions:
I-91 NB Exit 29 off-ramp has a single lane configuration, steep vertical grade with a significant volume of
heavy vehicles (11%). Traffic volumes are near capacity, at approximately 23,400 vehicles per day.
I-91 NB mainline experiences approximately 68,600 vehicles per day (vpd), and 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 (approximately 44,400 vpd) portion of the Charter Oak Bridge experiences heavy
weaving of vehicles entering from the I-91 NB off-ramp and continues to Route 15/I-84, with vehicles from
Route 15 traveling to Route 2 and Route 5, via the Exit 90 off-ramp.
Existing I-91 NB Exit 29
Improvements Include
Relocate I-91 Northbound Exit 29
Provide Two Lanes
Provide New Bridge (5 spans, 880’ long)
Widen I-91 Northbound
Extend Four-lane Section from Exit 27 to
Exit 29
Widen Route 15 Northbound
Provide Three Lanes from Charter Oak
Bridge to the Silver Lane Underpass

ramp. The new ramp will
be a major diverge, and
bridge over Route 5/15
before entering NB Route
5/15, and over the Charter
Oak Bridge.
