Customs and INS: Information on Inspection, Infrastructure,
Traffic Flow, and Security Matters at the Detroit Port of Entry
(22-APR-02, GAO-02-595R).
Concerns have been raised about the effects of heightened
security at two border crossings in Detroit--the Ambassador
Bridge and the Detroit-Windsor Tunnel. In the wake of September
11, the U.S. Customs Service and the Immigration and
Naturalization Service (INS) increased the number and
thoroughness of inspections and questioned all bridge and tunnel
travelers, leading to truck wait times that exceeded 10 hours. To
decrease wait times, Customs and INS extended shifts, curtailed
vacations, brought in more staff, and obtained help from the
National Guard and local law enforcement. The U.S. and Canadian
governments have agreed in principle to a plan to make the border
more secure without impeding traffic flow and trade. In addition
to increasing personnel and improving technology, officials are
considering pre-approval of low-risk traffic and reverse
inspections.

April 22, 2002 The Honorable John C. Conyers The Honorable Carolyn C.
Kilpatrick House of Representatives
Subject: Customs and INS: Information on Inspection, Infrastructure, Traffic
Flow, and Security Matters at the Detroit Port of Entry
In your November 6, 2001, letter, you expressed concern about the
postSeptember 11 environment of heightened security along our nation?s
borders, particularly regarding passenger and cargo delays at the two
Detroit Port of Entry land- border crossings. As agreed with your offices,
we obtained information on U. S. Customs Service and Immigration and
Naturalization Service (INS) inspection resources, traffic flow patterns,
inspection infrastructure issues, security issues, and potential long- term
solutions and options to increase traffic flow and enhance security at the
bridge and tunnel.
On February 20, 2002, we briefed your offices on the results of our review.
This report transmits the material from that briefing.
The Detroit area has two land- border crossings: the Ambassador Bridge and
the Detroit- Windsor Tunnel between Detroit, Michigan, and Windsor, Ontario.
Daily, thousands of cars and trucks cross over the bridge or use the tunnel.
Fiscal year 2001 traffic volumes over the bridge averaged approximately
10,800 passenger vehicles and 4,300 trucks each day, and the tunnel averaged
about 11,600 passenger vehicles and 240 trucks each day. Trade values
between the United States and Canada total about $1.2 billion per day, 27
percent of which is accounted for by merchandise crossing the Ambassador
Bridge alone. Both the bridge and tunnel are operational 24 hours a day, 7
days a week.
Immediately after September 11, Customs and INS increased the number and
thoroughness of inspections and questioned all bridge and tunnel travelers.
This effort resulted in truck wait times of over 10 hours in the
United States General Accounting Office Washington, DC 20548

first few days. 1 In an effort to decrease wait times, Customs and INS
extended shifts, curtailed vacations, and brought in additional staff and
obtained assistance from the National Guard and local law enforcement. By
the end of October, wait times had generally been reduced to about 20
minutes. However, Customs officials and bridge and tunnel officials said
that delays occur for other reasons, such as a limited number of bridge and
tunnel lanes, too few inspection booths, and various choke points, such as
the bridge cargo inspection plaza on the U. S. side. Increased security to
both structures was also implemented. Among the actions taken, bridge and
tunnel officials stopped allowing vehicles from queuing up on the bridge or
inside the tunnel. The vehicles are now held at either end of the facilities
until backups have diminished before they are allowed to cross the bridge or
use the tunnel.
Balancing enforcement of border security and facilitating travel and
commerce is a major challenge for Customs and INS inspectors assigned to our
borders. Some solutions are planned to be implemented to help reduce traffic
wait times. For example, Customs and INS expect to increase personnel.
According to the bridge and tunnel company officials, long- term
enhancements are possible at both locations. For example, the Detroit
International Bridge Company, a private company that owns the bridge, also
owns land near the bridge that could be used for expanded inspection space
on the U. S. side of the border. Company officials said, however, that
negotiations with the General Services Administration (GSA) 2 for one parcel
of land have been unsuccessful. Also, according to tunnel company officials,
the city of Detroit owns unused land adjacent to the tunnel that could
possibly be used to expand inspection facilities. However, no negotiations
had been completed at the time of our review.
A plan to make the border more secure without impeding travel flow and trade
has been agreed to in principle by the U. S. and Canadian governments. This
plan is the Canada- U. S. Smart Border Declaration, which was signed on
December 12, 2001, by the Office of Homeland Security Director and the
Canadian Minister of Foreign Affairs. The plan focuses on four primary
areas: the secure flow of people; the secure flow of goods; secure
infrastructure; and information sharing in the enforcement of these
objectives. The plan has listed 30 items for action to
1 Prior to September 11, 2001, no data exist about extent of delays. 2 GSA
is generally responsible for acquiring, leasing, and maintaining property
for use by U. S. government agencies.

improve border security and traffic flow. Many of the officials we
interviewed have suggested solutions for consideration that they believe
would facilitate the movement of traffic across the border and maintain
security of the bridge and tunnel.
Besides increasing personnel and improving technology to expedite the flow
of traffic, officials are also considering other procedures to improve
traffic flow and security. These include pre- approval of low- risk traffic
and reverse inspections. Pre- approved low- risk traffic would pass through
thus allowing for inspection efforts to concentrate on high- risk traffic.
Reverse inspections would involve U. S. inspectors clearing cargo and
travelers in Canada and vice- versa. Currently, vehicles leaving Canada are
not inspected until they reach the U. S. side of the border. Inspections,
under this plan, would be performed before trucks and travelers cross the
bridge or enter the tunnel instead of afterwards. However, proposals such as
reverse inspections are not without concerns and issues, and these are being
discussed at high U. S. and Canadian government levels.
To obtain information, we visited the Ambassador Bridge and DetroitWindsor
Tunnel from January 28 to January 31, 2002, and obtained preand post-
September 11 Customs and INS workload data. We met with Customs and INS
officials at their headquarters in Washington, D. C., and in Detroit; bridge
and tunnel operators; Detroit, Windsor, and Canadian Chambers of Commerce
officials; auto industry officials; and Canadian Consulate officials.
Overall, our work was conducted from December 2001 to February 2002 in
accordance with generally accepted government auditing standards.
The enclosed slides contain additional details on Customs and INS resources,
traffic volume at the ports of entry, security issues, and proposals for
long- term solutions. We provided Customs and INS with a draft of the slides
and incorporated their comments as appropriate. As agreed with your offices,
this report concludes our work on the Detroit Port of Entry border
crossings.

Traffic Flow Patterns (con?t.) Note: For the two delay spikes that occurred
after the end of October: November 8, 2001, was caused by vehicles being
held in a staging area to prevent them from sitting on the bridge, and the
other delay in November could not be explained by a Customs official.
