The alternatives envisioned for the 50km link are either a tunnel or a tunnel-bridge combination.

The pre-feasibility study is titled Talsinkifix, and the competitive tenders are invited by the Harju County government. The pre-feasibility study is intended to summarise previous studies and propose further steps. The main question to be explored in the study is the financial viability of a fixed Helsinki-Tallinn transport link and its economic impact.

The budget of the Talsinkifix study is approximately US$137,000.
