In 1862, the Bay of Honduras officially became a crown colony under the name British Honduras. By 1869, negotiations had stalled about the road. Guatemala and Britain tried to negotiate an Additional Convention, which Guatemala flatly rejected. Britain, using Guatemala's refusal, declared that they were free from the obligations of building the road. Guatemala did not agree, and stated the treaty was one of cession of territory with compensation being the road. Britain could never agree to the Guatemalan terms since that would break the 1850 Clayton-Bulwer Treaty as it's effectively a land deal. In 1871, Guatemala experienced a Liberal revolution and in 1884, cast doubts on Britain being compliant with the 1859 treaty. Guatemala never officially declared the treaty void at this time, however.
