Rhode Island’s Department of Transportation has begun placing 700-pound concrete blocks on manhole covers to prevent copper wire theft, a measure described as “low-tech but effective” in a report by The Drive. The initiative, part of a broader effort to combat the theft of wiring used in streetlamps, involves burying or flattening the blocks on roads or leaving them protruding off-road. RIDOT Interim Director Robert Rocchio stated the state has lost over $1 million in stolen copper, though he did not specify the timeframe. The program, costing $75,000, aims to install 151 blocks, with 87 already completed.
Copper wire theft has become a national issue, with reports of stolen cables leaving a Philadelphia youth football team without lighting and AT&T recording 4,300 thefts in California alone. Thieves typically cut cables, strip them for copper, and sell the metal, according to AT&T’s Scott Gonzaga. Rhode Island’s approach follows similar efforts in other states, though no other jurisdiction is noted to have used concrete blocks of this size. Rocchio described the strategy as “a constant battle,” emphasizing the difficulty of repairing stolen wiring before it is targeted again.
RIDOT’s Concrete Solution
The 700-pound concrete blocks are designed to deter theft by making manhole covers inaccessible without heavy equipment. RIDOT began deploying the blocks over the last few months, with officials stating the method has already shown effectiveness. The state’s program includes 151 total blocks, of which 87 have been installed. The cost of the initiative, $75,000, contrasts with earlier reports of a $750,000 figure, which a local news outlet later corrected.
National Context of Copper Theft
Copper wire theft is not unique to Rhode Island. In Philadelphia, stolen cables have disrupted public infrastructure, while California’s AT&T has launched awareness campaigns and reward programs to combat thefts. The process involves cutting cables, stripping them for copper, and burning the insulation to extract the metal. Though Rhode Island’s concrete blocks are a novel deterrent, the problem persists nationwide, with no mention of similar measures in other states within the sources.
Unanswered Questions
The sources do not specify whether the concrete blocks have reduced theft rates in Rhode Island or how often crews must return to address new incidents. The report does not specify the timeframe for the $1 million in losses or compare the effectiveness of the blocks to other anti-theft methods. The extent of copper theft beyond Rhode Island, Pennsylvania, and California is also未提及 in the sources.
