CONSTRUCTION WITH PRECAST

CONCRETE SECTIONS

REALIGNING BEAVER POND BROOK

The I-84 Waterbury Project includes unique

construction features — extensive in-water

work for the realignment of two rivers: the

Mad River, in the Plank Road/Reidville Drive

vicinity, and the Beaver Pond Brook, in the

Scott Road vicinity. Realignment of the water

bodies supports the successful realignment

of I-84 and its access ramps. Work, which

started in the spring, continues as the Beaver

Pond Brook is realigned along the existing

I-84 WB Exit 25 off ramp and along Plank

Road, to flow through two new culverts that

will carry the waterway under the roads (see

map at right). Once realigned, the Beaver

Pond Brook will flow through Culvert 014,

under Scott Road, and then through Culvert

06622, under the new Plank Road East.

Plank Road East will run parallel to future

I-84, in two directions, both east and west, to

Harpers Ferry Road.

Precast concrete sections (culvert

section being moved by crane below)

can be seen on various construction

sites within the project limits of the I-84

Waterbury Project. Each product is

uniquely designed for its ultimate

usage in retaining walls, culverts, and

drainage.

The series of photos below follow the construction of Culvert 06622, constructed using

22 precast interlocking concrete segments, to form a two-barrel box culvert.

BRIDGE CONSTRUCTION

I-84 and EB 25 Off Ramp Over Mad River, Western

Crossing (Bridge 1224): Workers set structural steel for

this bridge under construction on the southern side of the

existing/demolished I-84 bridge in the spring, and construction

of the decks continue this summer, with paving scheduled in

July. Once completed, drivers can anticipate traffic shifts onto

this new portion of the I-84 bridge so that demolition and

reconstruction of the north side of the bridge can commence.

The EB 25 off ramp will not be in use until the entire ramp,

that extends for almost a

mile, from west of the

Hamilton Avenue Bridge

overpass, crossing over

the Mad River twice, to

Harpers Ferry Road,

opens in 2017.

Bridge, on the western portion, from north to south over I-84.

SETTING STRUCTURAL STEEL

Hamilton Avenue Bridge (Bridge 4321): As the Project will

widen I-84 to three lanes in each direction, the existing bridge

must be lengthened to accommodate not only the additional

lanes, but also the EB 25 off ramp. This requires spanning all

new structural steel across I-84, from the newly constructed

abutment on the north side, over two center piers, to the

abutment on the south side. As the steel girders had to be

placed and secured over travel lanes of I-84, the structural

steel was erected during the night time hours. For safety

purposes, I-84 was closed at Exit 23 in both directions to

prevent travelers from entering the active work zone during

splicing of girder sections. Motorists were guided through the

detour route by construction signage, State, and local Police.

The photo to the right depicts

where the steel decks are

currently under construction,

CONSTRUCTION OFF THE MAINLINE

West of Harpers Ferry Road: Construction of the new I-84

bridge and new EB 25 off ramp over the Mad River (eastern

crossing) continues with abutment construction visible on both

banks of the river (photo of sites below). The new EB 25 off

ramp will rise to meet the new Harpers Ferry Road. These

bridges are currently under construction south of the existing

highway. Once these structures are complete and open to

traffic, the existing section of I-84 will be demolished.

Harpers Ferry Road Bridge will be realigned, and construction

for the footings for the southern abutment and pier stem for

the new bridge is underway. The new abutment and pier stem

footings run almost parallel to the existing highway on the

easternmost bank of the Mad River, south of I-84.

Outreach to Residents

The Public Information Team directly engages with residents

and businesses within areas of potentially unexpected

disruptive construction activities to make them aware of work

that is scheduled to take place. The team was invited by the

Bouley Manor Neighborhood Association to present project

updates during its

monthly meeting

on June 9th

(photo on right).
