Alexander Hamilton Bridge HistoryAlexander Hamilton Bridge History
A new eight-lane arch span was
proposed - the Alexander Hamilton
Bridge – to connect the Trans-
Manhattan and Cross-Bronx
Expressways.
Currently, estimated traffic
over the Hamilton Bridge
is over 188,000 vehicles
per day.
The Alexander Hamilton
Bridge has not undergone
major repair since it opened
on January 15, 1963.
In 1955, Robert Moses determined that
the 181st
Street Bridge would not be able
handle the anticipated traffic demands
from the proposed lower level of the
George Washington Bridge.

Editor's Notes
Stage 1 : The median area will be reconstructed as a temporary travel lane
Stage 2: The westbound right-hand lanes will be worked on and the bridge will be widened
Stage 3: The eastbound right-hand lanes will be worked on and the bridge will be widened
Stage 4: Eastbound traffic will be split, with the construction work area in between
Stage 5: Westbound traffic will be split, with the construction work area in between
Stage 6: Traffic will return to its original formation, and the median barrier will be reconstructed
The arch rib will require stiffening only to the outer ribs, and primarily to reinforce these members for section loss due to corrosion.
The only spandrel columns that require reinforcement are the longest columns at Panel Points 8 and 8’. This is because the original design used the same section for all columns, and buckling controlled the design.
Load capacity increase is assisted by making the slab composite
And finally it is proposed to eliminate the expansion joints in the deck at the 1/3 points. The analysis of the overall combined structure indicated that no overstresses resulted provided that the joints were locked at the full dead load condition.
Referred to as “spaghetti ramps”
Field Automated Communications Systems - FACS
Acceleration analysis – our independent analysis verified Contractor’s analysis and also showed additional areas that could be accelerated to meet goals
Submittal review analysis – if review process can be shortened what is result
Fabrication review analysis – if fabrication duration can be shortened what is result
Extensive analysis of mitigation options and ideas
Will modifying stages actually save time?
While we are working on mitigation ideas, what work should we be progressing
Will moving west approach slab work earlier actually help?
If we keep Temporary Bridge 7A in service longer, will it hurt us later?
By-in by NYSDOT Management is key
Enterprise system is working so well because NYSDOT has made it clear that this is the way they want to do business on this project
NYSDOT Area Supervisor chaired schedule kick-off meeting at start of project – I want this system to work and to be used
Involved in weekly schedule meetings
Does not work well on other projects if senior DOT staff is not on board and
Software Notebook Function is Excellent Tool
Speeds development of monthly schedule narrative
Excellent record of changes
Have already applied this to other projects
Provide Schedule Template to Contractor
Speeds creation of baseline
Uniform standard DOT calendars and codes
Minimum bid price for scheduling
Contractor hired qualified scheduler
Two bidders bid more than minimum
Shows that scheduling is very important
Schedule Specification
Immediate rejection criteria – avoids incomplete schedule submissions made just to meet deadlines or get paid
Details how schedule should be calculated
If you maintain the integrity of the schedule you can actually use it to manage the project
What-if scenarios to model mitigation options or potential impacts
Model acceleration to set expected goals
Model impact of stage changes
