The Padma Bridge Toll: Balancing Economy and Equity
You are a member of the Bangladesh Bridge Authority's advisory committee. The Padma Bridge, funded entirely by Bangladesh, has been operational for two years. The toll revenue is BDT 1,500 crore per year, but maintenance and loan repayment cost BDT 1,200 crore annually. The government is considering raising tolls by 25% to generate more revenue. However, a study shows that a 25% increase would reduce traffic by 15%, hurting small traders and farmers who rely on the bridge to transport goods to Dhaka. The bridge has reduced travel time between Dhaka and 21 southwestern districts by 4 hours, boosting the regional economy by an estimated BDT 5,000 crore per year. The government also wants to recover the construction cost of BDT 30,000 crore within 20 years. The committee must recommend a toll policy that balances revenue, equity, and economic growth. You have data showing that heavy vehicles pay 60% of tolls but cause 80% of wear and tear.
1. What factors should the committee consider in recommending a toll policy? Provide a reasoned recommendation.

The committee should consider: (1) Revenue sufficiency to cover maintenance and loan repayment; (2) Equity for small traders and farmers; (3) Economic efficiency – tolls should reflect the cost of infrastructure use; (4) Elasticity – traffic response to price changes; (5) Wear and tear – heavy vehicles cause disproportionate damage; (6) Alternative routes – if tolls are too high, traffic may divert, reducing revenue.
Recommendation: Adopt a differentiated toll structure. Increase tolls for heavy vehicles (trucks and buses) by 30%, while keeping small car and motorcycle tolls unchanged or increasing them by only 5%. This targets those who cause more damage and can afford to pay, while protecting small traders. Introduce a monthly pass for farmers transporting agricultural goods, with a 50% discount, to support the agricultural economy. The revenue impact: heavy vehicles contribute 60% of current tolls, so a 30% increase on them adds about BDT 270 crore, while a 5% increase on light vehicles adds about BDT 30 crore, totaling BDT 300 crore, which compensates for the 15% traffic reduction among heavy vehicles (if elasticity is -0.6). This policy balances revenue, equity, and efficiency. The committee should also recommend a periodic review every three years and a transparent toll-setting formula linked to inflation and maintenance costs.
2. How would you address the concerns of small traders and farmers who fear the toll increase will hurt their livelihoods?

I would propose targeted mitigation measures: (1) Subsidized passes: For registered small traders and farmer cooperatives, offer a digital pass with a 50% discount on tolls, funded by the additional revenue from heavy vehicles. (2) Improve alternative routes: Invest in feeder roads and water transport to reduce dependence on the bridge for short-distance trips. (3) Consultation: Hold public hearings in the southwestern districts to hear their concerns and adjust the policy. (4) Support local markets: Develop cold storage and market facilities in the southwest so that farmers do not need to transport perishables to Dhaka as frequently. (5) Transparency: Publish the toll policy and the rationale, including the wear-and-tear data, so that stakeholders understand the fairness of the structure. These measures would show that the government is not ignoring equity while ensuring the bridge remains financially sustainable.
