Botley Road, a main route into the city centre, reopened this week after being closed for over three years while Network Rail worked to replace a railway bridge.
The project, which also included plans for a new platform and entrance to the station, was intended to enhance track capacity.
Originally budgeted at £161 million, the project is now significantly overdue and over budget, with key elements such as the platform and station entrance still unfinished.
The bridge itself is 18 metres wide and spans a two-lane road.
Writing for The Spectator Sam Dumitriu notes that the The Clifton Suspension Bridge, designed by Isambard Kingdom Brunel over 150 years ago, remains a notable example of civil engineering.
Sam Dumitriu said recent studies have shown that building infrastructure in Britain is generally more expensive than in countries like France and Germany.
A report by Britain Remade and the Centre for British Progress found a 65 per cent higher construction cost in Britain compared to its European counterparts, with rail projects being 79 per cent more expensive.

The high cost of the Botley Road bridge replacement was largely due to unforeseen issues beneath the road.
Oxfordshire Council had planned to lower the road to allow double-decker buses to pass under the bridge, and to add cycle lanes and pedestrian space.
However, contractors were unaware of the true size of a Victorian arch under the road, which turned out to be three times larger than expected.
They also found pipes and wires in worse condition and closer together than anticipated.
These issues led to significant delays as solutions had to be negotiated between Thames Water and Network Rail, a process which took nearly nine months.
Sam Dumitriu asserts that Network Rail had not carried out the necessary surveys and investigations before closing the road.
They relied on ground-penetrating radar, which did not reveal the full extent of the issues.
The failure to conduct thorough surveys echoes past mistakes.
For instance Sam Dumitriu highlight that when electrifying the Great Western Mainline, Network Rail also underestimated the complexities of dealing with Victorian rail bridges, leading to a 70 per cent budget overrun.
In Edinburgh, lessons were learned after the first phase of building a tram system ran late and over budget due to unexpected utility issues.
More extensive surveys and better management led to the second phase being delivered on time and within budget.
The Botley Road project serves as a reminder of the importance of thorough planning and accountability in infrastructure projects.
